The resistance of the solenoid needs to be 3.30 N and the magnetic field of the solenoid with a current of 2.90 A should be 5.10 x 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 Q:m for the resistivity of copper.)
