Question

An electric field of 4.0 μ V/m is induced at a point 2.0 cm from the axis of a long solenoid (radius = 3.0 cm, 800 turns/m). At what rate in A/s is the current in the solenoid changing at this instant? a. 0.50 b. 0.40 c. 0.60 d. 0.70 e. 0.27

Answer 1

Its 0.7628 because if you mutiply and moilowt it then toy get the jsd
