1) You have designed and constructed a solenoid to produce a magnetic field equal in magnitude to that of the Earth (5.0 x 10^-5 T). If your solenoid has 400 turns and is 32 cmlong, determine the current you must use in order to obtain a magnetic field of the desired magnitude.

2) A single turn coil of radius 4.50 cm is held in a vertical plane and a magnet is rapidly moved relative to the coil as shown in the diagram below.

The field inside the coil changes from 0.490 T to 0.355 T in 0.120 s. If the resistance of the coil is 3.30 Ω, what are the magnitude and direction of the induced current in the coil as viewed from the side of the magnet?
