A coil of wire carrying a current in a magnetic field experiences a force that tends to make it rotate. This effect can be used to make an electric motor.
What causes the rotation in an electric motor?
Magnetic fields cause motors to rotate. … A coil of wire carrying a current in a magnetic field tends to rotate. This is the basis of an electric motor. The force on a conductor in a magnetic field causes the rotation of the coil in an electric motor.
What factors will affect the rotation of the simple electric motor?
The rotating speed of an electric motor depends on two factors: its physical construction, and the frequency (Hz) of the voltage supply. Electrical engineers select the speed of a motor based on the needs of each application, similar to how the mechanical load determines the horsepower required.
How do you make an electric motor spin faster?
The speed of rotation of the coil can be increased by:
- increasing the size of the current;
- using a stronger magnet;
- increasing the number of turns of wire in the coil;
- reducing friction between the coil and the axel it rotates on.
