Question

A long solenoid with length I = 1.20 m and a cross-sectional area A = 4.00 cm2 consists
of N1 = 1260 turns of wire. An insulated coil of N2 = 945 turns is wrapped around it, as
shown in Figure. Assume that all the flux from the solenoid passes through the outer coil.
If the current in the solenoid drops uniformly from 18.0 A to zero in 6.00 ms, determine
the emf, in V, induced in the outer coil.

For a physics lab assignment, a student needs to create a solenoid using copper wire with diameter d = 0.500 mm. The resistance of the solenoid needs to be 3.50 and the magnetic field of the solenoid with a current of 2.90 A should be 5.90 × 10-² T. Assume the resistance does not change significantly with temperature, and the radius of the solenoid is 1.00 cm. (Use p 1.70 x 10-8.m for the resistivity of copper.)
