Question

Name some devices based on electromagnetic induction.

Answer 1

Step 1: Electromagnetic induction :

• In 1831, Michael Faraday discovered electromagnetic induction, which was mathematically characterized by James Clerk Maxwell as Faraday's law of induction.
• According to Electromagnetic Induction, the EMF is generated in the conductor when the magnetic flux associated with the coil changes or the moving conductor cuts the magnetic flux and the induced EMF creates a current flow in the closed-loop known as the Induced current.

Step 2: Some devices based on electromagnetic induction

• Electric generator
• Transformer
• Moving coil galvanometer
• Induction cooker
