A solenoid of radius 2.60 cm has 350 turns and a length of 15.0 cm.
(a) Find its inductance.
=___mH
(b) Find the rate at which current must change through it to
produce an emf of 72.0
a) Inductance of solenoid, L = mue*N^2*A/l
= 4*pi*10^-7*350^2*(pi*0.026^2)/0.15
= 2.18*10^-3 H
= 2.18 mH
b) Induced emf = L*dI/dt
==> dI/dt = induced emf/L
= 72*10^-6/(2.18*10^-3)
= 33 mA/s
