Consider the situation in Exercise 29.21. In part (a), find the direction of the force that the large circuit exerts on the small one. Explain how this result is consistent with Lenz€™s law.

Data from exercise 29.21

A small, circular ring is inside a larger loop that is connected to a battery and a switch (Fig. E29.21). Use Lenz€™s law to find the direction of the current induced in the small ring.
