A circular coil and a bar magnet recede from cach other with the same velocity. Then

Options

A. there will be no induced emf in the coil
B. there will be an induced emf in the coil
C. an emf will be induced in the magnet
D. none of these

Answer

### Step-by-Step Solution:

1. **Understanding the Situation**: We have a circular coil and a bar magnet that are moving away from each other at the same velocity.

2. **Relative Motion**: When two objects move away from each other with the same velocity, from the perspective of either object, they appear to be at rest relative to each other. This means that there is no change in the distance between them in terms of their relative motion.

3. **Induced EMF Concept**: According to Faraday's law of electromagnetic induction, an electromotive force (EMF) is induced in a coil when there is a change in magnetic flux through the coil. The key factor here is that there must be relative motion between the magnet and the coil to change the magnetic flux.

4. **Analyzing the Situation**: Since the coil and the magnet are receding from each other with the same velocity, there is no change in the magnetic flux linked with the coil. Therefore, there will be no induced EMF in the coil.

5. **Conclusion**: Based on the above analysis, we conclude that:
- There will be no induced EMF in the coil.
- The other options regarding induced EMF in the coil or the magnet are incorrect.

### Final Answer:
- There will be no induced EMF in the coil.
