The magnetic effect of electric current is used in which of the following devices?
Explanation
The magnetic effect of electric current is the principle behind the operation of devices like motors.
When a current flows through a wire, it creates a magnetic field around it. In a motor, this magnetic field interacts with permanent magnets to cause a coil to rotate
This rotation then drives the motor. Electric fans utilize this principle to spin their blades.
