The battery discussed in the previous question is suddenly disconnected. Is a current induced in the other loop? If yes, when does it start and when does it end? Do the loops attract each other or repel?

no the loops attract each other

Explanation:
- Upon sudden disconnection of the battery, a current is caused in loop B due to a sudden flux shift through it.
- This is triggered only for a moment when the current falls to zero abruptly. After it has dropped to zero there is no induced current.
- The induced current is such as to increase the rising magnetic field according to Lenz's law.
- So if the current in loop A is in the direction of the clock, then the induced current in loop B will also be in the direction of the clock. Thus, the two loops will attract one another.
