A wire loop with a resistance, R = 0.174 Ohms is pulled to the right out of a region with a uniform magnetic field B = 0.468 T  that points out of the screen as shown in the diagram below. As is moves, out of the field region, a current is induced, because of the current, there is a magnetic force on the loop. How much force (magnitude only) is required to keep the loop moving at a constant speed of v = 17.0 m/s? The height of the loop, L = 0.189 m. Please give your answer in Newtons.

An N-turn square coil with side and resistance R is pulled to the right at constant speed v in the presence of a uniform magnetic field B acting perpendicular to the coil as shown in the figure below.

The diagram below depicts a rectangular wire loop of width a = 17.5 cm and height b = 7.95 cm, that is connected to a current source that when turned on, gives rise to a current I = 0.35 A in the wire. The loop is suspended in a uniform magnetic field B = 0.85 T that points in a vertical direction as shown in the diagram, and it would hang vertically if there were no current in the wire. We assume that the wire is massless, but two masses m = 9 g are suspended at the lower corners. What is the angle, θ, at which the loop is in equilibrium?

A conducting facet (L = 10[cm]) moves to the right on two frictionless conducting rails, as shown in the figure. The magnetic field in the region has a direction perpendicular to the plane of the rails and is uniform and constant. If a constant force F = 0.6 [N] moves the bar at a constant speed of v = 2 m/s, what is the current through the 12 ohm resistor? Express your answer in amperes, rounding to two decimal places. 1292 L

The figure below shows a piece of insulated wire formed into the shape of a figure eight. You may consider the two loops of the figure eight to be circles, where the upper loop's radius is 3.00 cm and the lower loop's radius is 8.00 cm. The wire has a uniform resistance per unit length of 4.00 0/m.

Refer To: Ref 22-2 Which one of the following statements concerning this situation is true? Since the circuit moves with constant speed, the force F does zero work. The induced current flows clockwise around the circuit. As the circuit moves through the field, the field does work to produce the current. If the circuit were replaced with a wooden loop, there would be no induced emf. The temperature of the circuit remains constant.
