Make a simple Linear Motor
A linear motor is an electric motor that has had its stator and rotor “unrolled” so that instead of producing a torque (rotation) it produces a linear force along its length. The most common mode of operation is as a Lorentz-type actuator, in which the applied force is linearly proportional to the current and the magnetic field
How to make a simple Linear Motor Experiment
for make of this motor you need following things
aluminum pipe or steel pipe, mechanical pencil lead, magnet, battery and conducting wire.
