Question

Assume that both coil and magnet are moving with the same velocity with respect to the ground. Would there be any emf induced in the coil? What will happen if both are moving at the same speed but in opposite direction?

Answer 1

Step 1: Introduction

As per the given statement,

It is explained below both the fields at the different states.

Step 2: Explanation

• When we assume that both coil and magnet are moving with the same velocity or the same direction then there will be no relative speed of motion.
• Hence, The emf induced in the coil with respect to the magnet will be zero.
• If both coil and magnet are moving at the same speed but in the opposite directions then, Any magnetic field which is produced by the induced current will travel in the opposite direction to the change in the actual field of movement.

Step 3: Final Answer

As per the above explanation, it is concluded that :

“when there will be no relative speed of motion and the emf induced in the coil with respect to the magnet will be zero.”

“Any magnetic field which is produced by the induced current will travel in the opposite direction to the change in the actual field of movement.”
