Disadvantages are high maintenance and low life-span for high This should be applied to the bottom of each magnet before placing. Magnetic minerals in rocks can lock-in a record of the direction and intensity of the magnetic field when they form. An electric motor is an electrical machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. A 1/2 diameter x 1/8 thick neodymium magnet loses almost a 1/3 of its power in an 1/8 of distance.
