Which of the following devices uses the magnetic effects of current? (2023)
Step 1: Understand what is meant by 'magnetic effects of current'. This refers to how electric current can create a magnetic field.
Step 2: Identify devices that use this principle. An electric motor is one such device.
Step 3: Learn how an electric motor works. It takes electrical energy and uses the magnetic field created by the current to produce movement (mechanical energy).
Step 4: Conclude that the electric motor is the device that uses the magnetic effects of current.
