Question 3: Induction (a) The rod shown below moves to the right on essentially zero-resistance rails at a speed of v = 3.0m/s. If B = 0.75T everywhere in the region, what is the current through the 5.02 resistor? 5.0 Ω 4.0 cm A circular loop of wire of radius 10 cm is mounted on a vertical shaft and rotated at a frequency ofw = 50 RPM in a region of uniform magnetic field of B= 200mT perpendicular to the axis of rotation. (b) Find an expression for the time-dependent flux, (t), through the ring. (c) Determine the time- dependent current, 1(t), through the ring if it has a resistance of 10 0. (1)
