1. The problem statement, all variables and given/known data

2. Relevant equations

$$E=-M\frac{di}{dt}$$

3. The attempt at a solution

Can anyone even tell me what the heck this problem is asking? This chapter has been a nightmare and I don't understand any of it. The book is terrible and barely explains what 'mutual inductance' even is. The sample problems are ridiculous too.
