There is a figure below shows a single-turn rectangular-shaped circuit with a width, w = 0.123 m, and height, h = 0.0893 m. The circuit contains a R = 23.0 Ω resistor. The circuit is immersed in a uniform magnetic field which points out of the plane of the circuit. (a) In order to induce a clockwise current in the circuit, should the magnetic field strength increase or decrease? (b) In order to induce a clockwise current of | = 4.23 A in the circuit, what must be the rate of change of the magnetic field, ΔB/Δt?? If the magnetic field is decreasing, include a - sign; if the magnetic field is increasing, include a +sign. (c) Suppose the circuit below had 78 turns. In order to induce a clockwise current of | = 4.23 A in the circuit, what must be the rate of change of the magnetic field, ΔB/Δt? now?
