The magnetic effect of electric current is used in which of the following devices?
Answer: Electric bulbs and fans
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.
