Two coils, held in fixed positions, have a mutual inductance of m = 0.0034 h. the current in the first coil is i(t) = i0sin(ωt), where i0 = 5.4 a, ω = 143 rad/s.

m = 0.0034 h i0 = 5.4 a ω = 143 rad/s

(a) express the magnitude of the induced emf in the second coil, ε2, in terms of m and i.
(b) express the magnitude of ε2 in terms of m, io, and ω.
(c) express the maximum value of |ε2|, εmax, in terms of m, i0, and ω.
(d) calculate the numerical value of εmax in v.
