Abstract: The main objective of this work is to study the free energy permanent magnet motor, where the natural repulsion or attraction characteristics of magnet poles creates a perpetual motion which can be harnessed by the magnet motor. The essential idea of this work has started by taking advantages of permanent magnet properties in these machines when replacing electric coils by permanent magnets, to build a free energy magnetic motor. The design of rotor drum plays a vital role in these magnetic motor where the magnetic field and repelling force is when the magnets is separated by a definite distance is considered. The simulation is done using a matlab software where the electrical parameters are simulated using the magnet properties and electrical equations. The materials were selected according to the characteristics and influencing factor such as temperature, weight and stored energy. The permanent magnets have invisible and continuous power where it can attract the iron or other specific kind of metal with the energy flow which allows the permanent magnet to defy the gravity for years. Therefore, it is believed that the free energy can be extracted from the permanents magnets by arranging the magnets in special configuration.

I. INTRODUCTION Natural resources are commonly divided between renewable resources and non-renewable resources use of either of these former of resources beyond their rate of replacement is considered to be resources depletion. The value of resources is direct result of it availability in nature and the cost of extracting the resources, the more a resources is depleted the more value of the resources increases. These are several types of resources depletion the most known being; Aquifer depletion, deforestation, mining for fossil fuels and minerals. Pollution, flash and burn agriculture practice, soil erosion, and overconsumption, exercise or unnecessary use of resources. All energy sources have some impact on our environment fossil fuels -Coal, oil and natural gas- do substantially more harm than renewable energy source by most measure, including air and water measure, including air and water measures, including air and water pollution, damage to public health wildlife and habitat loss, water use, land use and global warming emissions.

II. PRINCIPLE OF ENERGY A free energy magnet motor uses its natural properties such as attraction and repulsion of the magnet poles to create a perpetual motion which can be harnessed to do a useful work. The permanent magnets have invisible and continuous power where it can attract the iron or another specific kind of metal with the energy flow which allows the permanent magnet to defy the gravity for years. Therefore, it is believed that the free energy can be extracted from the permanent magnets by arranging the magnets in a special configuration. Similar to the solar panel does not put effort into producing. Magnet Engine free energy generator is an easy device to generate electrical energy. It works on the principle of Neodymium Magnets. In a simple motor, magnetic field is created by the electric coils generally Cu, Al coils. These motors continuously need electrical supply to produce magnetic field. There is huge amount of energy losses. But the Magnet Motor Consists of no such coils. Hence there will be minimal losses. It uses the permanent magnetic field of the magnets to generate the required force to move the motor. This concept of generating magnetic field from the permanent magnets became practical only after introducing Neodymium magnets

which are much power full than the previous Ferrite magnets. The main advantage is that it does not require continuous electric supply.

III. DESIGN OF MAGNETIC MOTOR The basic idea of designing a magnetic motor is by considering the 2 basic concepts. One the principle of magnets that is when two magnets are placed with their like poles facing each other, the lines of force are in opposite directions and hence like poles repel each other. When the unlike poles of a bar magnet face each other the magnetic lines of force are in the same direction and hence unlike poles attract each other, and the other is by considering the pull force created by the repulsion effect.

A. Design of A Rotor Drum The whole rotor drum circumference is 292.5 mm where the magnets are placed. To design the way in which the magnets are placed on circumference of nylon drum the whole circumference of nylon drum is divided into 3 section each of 85 mm and a spacing of 12.5 mm between each section.

Figure 1: Design of single section of rotor drum The magnetic field strength at the midpoint of a horizontally placed magnet that is at 32.5 mm horizontally is calculated using a K&J magnetic field calculator is 116.4 gauss at an angle of 180.2 degree as shown in fig. 2 There are 2 compensating magnets used to compensate magnetic field strength as well as to improve the repelling force.

As magnets are separated by a few distance of millimeter the magnetic field lines of one magnet and another magnet coincide due to which the magnetic field strength also increases, so at the midpoint of magnet placed in any direction is twice the calculated value. The magnitude of magnetic field strength at the midpoint of two magnets considering any of the two magnets magnetic field coinciding with each other is calculated and tabulated in the table 1 below

Table I: Magnetic Field Strength Between the Magnets Considered (Between 2 Magnets) Considering the point that the magnets are placed so closely due to which a magnetic field strength in the rotor increases considering the point where the three or more magnets magnetic field lines coincide its field strength is calculated and tabulated in table 2.

B. Design of Stator Part At stator we have used a linear actuator to trigger the movement initially and during the rotation of rotor it creates the repelling force constantly within the rotor magnet and the stator magnet, so the rotor does not stop rotating at any point. Neodymium magnet of length 120 mm, width of 15 mm and thickness of 4 mm ND 52 grade magnet is used, and it is fitted to the moving part of the linear actuator. Where its moving stroke varies from minimum of 3 mm and maximum of 10 mm. There will be difference in repelling force due to the change in distance between the rotor magnets and stator magnet. Table 3 shows the repelling force between the magnets is calculated using the K&J repelling force calculator and its graphical representation is shown in fig. 3.

A. Operation of Simulink Calculation of theta involves conversion of radians to degree and a discrete time integration function block and modulus math function. Consider 100 radians as a constant and then convert these 100 radians into degrees by using the formula 180/pi using a gain function block. The gain block multiples the input by a constant value in an element wise multiplication method. The magnetic flux through some surface is proportional to the number of field lines passing through that surface. Φ=B*A cos θ (1) The magnetic flux passing through a surface of vector area A. First the simulated value of theta is taken as an input to the trigonometric function block where the cos is set as an operating function to the block, then the known values of magnetic field and surface area of magnet calculated using surface area of cylinder formula = 2ℎ + 22 (2) Faraday’s experiments showed that the EMF induced by a change in magnetic flux depends on only a few factors. First, EMF is directly proportional to the change in flux Δ. Second, EMF is greatest when the change in time Δt is smallest that is, EMF is inversely proportional to Δt. d VN (3) dt Finally, if a coil has N turns, an EMF will be produced that is N times greater than for a single coil, so that EMF is directly proportional to N. The value of current can be calculated using a formula of magnetic flux linkage that is  IN (4) L Where: L is inductance in Henry, N is the Number of Turns Φ is the Magnetic Flux, Ι is in Amperes To calculate the value of inductance L NA2 L   (5) 0 I

VI. WORKING PRINCIPLE A free energy magnet motor uses its natural properties such as attraction and repulsion of the magnet poles to create a perpetual motion which can be harnessed to do a useful work. The permanent magnets have invisible and continuous power where it can attract the iron or another specific kind of metal with the energy flow which allows the permanent magnet to defy the gravity for years. Therefore, it is believed that the free energy can be extracted from the permanent magnets by arranging the magnets in a special configuration. Similar to the solar panel does not put effort into producing. This is the reason that magnet can attract the iron or another specific kind of metal with the energy flow that is so called “magnetism”. This energy flow allows the magnet to defy the gravity for years on end. This property of magnet is believed that have the capabilities to create an indefinite source of energy. Through the concept of the natural polarity of the magnetic poles that the like poles repel each other, unlike poles attract each other. The natural repulsion or the repelling characteristics of magnetic waves creates a perpetual motion that is being harnessed by the magnetic devices electricity, the power of a magnet flows from the environment and not from the magnet. Magnet Engine free energy generator is an easy device to generate electrical energy. It works on the principle of Neodymium Magnets. In a simple motor, magnetic field is created by the electric coils generally Cu, Al coils. These motors continuously need electrical supply to produce magnetic field. There is huge amount of energy losses. But the Magnet Motor Consists of no such coils. Hence there will be minimal losses. It uses the permanent magnetic field of the magnets to generate the required force to move the motor. This concept of generating magnetic field from the permanent magnets became practical only after introducing Neodymium magnets which are much power full than the previous Ferrite magnets. The main advantage is that it does not require continuous electric supply.

VII. CONCLUSION The point of the magnetic motor is to provide an alternative energy source so that we do not have to independently rely on fossil fuels. The magnets are not doing harm to environment. The biggest issue is going to be the cost of the replacement magnets. A magnet motor energy generator works but science behind this revolutionary concept needs some more developing and work through to become reliable energy source to reduce our dependence on fossil fuels. Permanent magnet motors and generators offer several advantages like decreased installation space for higher power and unnecessary gearboxes. Designing and producing these high-speed permanent magnet motors and generators is an exciting task, where the usage of most modern computational methods for the development process is as important as a wide range of experience and expertise to extend actual operation limitations in a safe way. This design may prove to be a pioneer in the field of research of free energy. This concept of free energy is can be made using magnets and simple motors.
