.. When the magnetic flux through a single loop of wire increases by 30T•M², an average current of 40 A is induced in the wire. Assuming that the wire has a resis- tance of 2.5 N, (a) over what period of time did the flux increase? (b) If the current had been only 20 A, how long would the flux increase have taken?
