A square loop of wire is pulled at constant speed out of a uniform magnetic field that points into the page. (a) Describe the direction of the induced current in the loop.(b) What causes this current to be induced?(c) If the speed of the loop is increased, how does that affect the magnitude of the induced current?

A single rectangular wire loop of dimensions 0.20 m×0.30 m0.20\,\text{m} \times 0.30\,\text{m} is pulled out of a uniform 0.50 T0.50\,\text{T} magnetic field at a speed of 2.0 m/s2.0\,\text{m/s}. The magnetic field is perpendicular to the plane of the loop and into the page. (a) Calculate the change in magnetic flux as the loop completely leaves the field.(b) If the loop takes 0.10 s0.10\,\text{s} to exit the field, what is the average induced EMF?(c) If the loop has a total resistance of 2.0 Ω2.0\,\Omega, what is the average induced current?

A 10.0 μF10.0\,\mu\text{F} capacitor is connected in series with a 5.0 kΩ5.0\,\text{k}\Omega resistor and a 12.0 V12.0\,\text{V} battery. (a) Calculate the time constant τ\tau for the circuit.(b) What is the voltage across the capacitor after 2.0 s2.0\,\text{s} of charging?(c) How much charge is on the capacitor at that time?
