Suppose the resistance of the coil in the previous problem is `25Omega`. Assume that the coil moves with uniform velocity during its removal and restoration. Find the thermal energy developed in the coil during (a) its removal, (b) its restoration and (c) its motion.

Explanation

To solve the problem, we need to calculate the thermal energy developed in the coil during three different scenarios: (a) its removal from the magnetic field, (b) its restoration back into the magnetic field, and (c) during its motion.

### Given Data:
- Resistance of the coil, \( R = 25 \, \Omega \)
- Length of each side of the square coil, \( l = 0.5 \, m \) (50 cm)
- Number of turns, \( N = 50 \)
- Magnetic field strength, \( B = 1 \, T \)
- Time taken for removal and restoration, \( t = 0.25 \, s \)
