A large research solenoid has a self-inductance of 25.0 H. (a) What induced emf opposes shutting it

Question:

A large research solenoid has a self-inductance of 25.0 H.

(a) What induced emf opposes shutting it off when 100 A of current through it is switched off in 80.0 ms?

(b) How much energy is stored in the inductor at full current?

(d) In view of the answer to the last part, is it surprising that shutting it down this quickly is difficult?
