A conducting rod slides along the metal rails as shown below. The apparatus is in a uniform magnetic field of strength 0.25 T, which is directly into the page. The rod is pulled to the right at a constant speed of 5.0 m/s by a force F→. The only significant resistance in the circuit comes from the resistor shown. Find (a) emf and (b) current induced in the circuit. ε = 0.4 V, I = 0.125 A ε = 0.050 mV, I = 25 mA ε = 0.050 mV, I = 25 mA

A coil of 15 turns and radius 10.0 cm surrounds a long solenoid of radius 2.20 cm and 1.00×103 turns/meter (see figure below). The current in the solenoid changes as I = 3.00 sin⁡120 t, where I is in amperes and t is in seconds. Find the induced emf (in volts) in the 15-turn coil as a function of time. ε =
