How do electric motors work physics?
A simple electric motor can be built using a coil of wire that is free to rotate between two opposite magnetic poles. When an electric current flows through the coil, the coil experiences a force and moves. … When the electric current changes direction, the same end of the electromagnet becomes its south pole.
What is an electric motor and how does it work?
An electric motor is a device used to convert electricity into mechanical energy—opposite to an electric generator. They operate using principles of electromagnetism, which shows that a force is applied when an electric current is present in a magnetic field.
How does a motor rotate?
The current-carrying wire in a magnetic field results in a force which will rotate the rotor. top conductor (“a”) of the armature loop towards the left, and acts to pull the lower conductor (“b”) towards the right. These two forces rotate the armature that is attached to the rotor.
What does a motor do?
A motor converts electrical energy into mechanical energy. It is estimated that nearly half of the world’s energy consumption is consumed by motors.
How does an electric motor work ks3?
Electric motors use the forces produced by magnetic fields to produce a turning motion. If you put a length of wire in a magnetic field and pass a DC current through it (such as from a battery), the wire will move. This is called the motor effect .
How does an electric motor work class 10?
The electric motor works on the principle that when a coil is placed in the magnetic field and the current passes through it resulting in rotation of the coil.
