a) As alternating current flows through the coiled wire, explain how it affects the magnet's movement.
b) Describe the process that causes the magnet to rotate in an AC motor.
c) Differentiate between the mechanisms involved in an AC motor affecting the magnet's rotation.
d) Analyze the relationship between alternating current and the magnet's movement in an AC motor.

Answer 1

The magnet rotates in an AC motor due to the interaction between the magnetic field and the alternating current flowing through the wire.

Step-by-step explanation:

Electric motors convert electrical energy into mechanical energy by utilizing magnetic force on current-carrying wires. In an AC motor, which stands for alternating current motor, the magnet rotates due to the interaction between the magnetic field and the alternating current flowing through the coiled wire.

As the alternating current flows through the wire, it creates a magnetic field around the wire. This magnetic field interacts with the permanent magnet, causing a torque or rotational force on the magnet. The direction of the torque reverses every half rotation, ensuring continuous rotation of the magnet.
