A conducting rod with a length of 27.0 cm is placed on a U-shaped metal wire that includes a light bulb with a resistance of 80.0 Q as shown in Figure. A constant magnetic field with a strength of 0.600 T is applied perpendicular into the paper. An applied force moves the rod to the right with a constant speed of 6.00 m/s. What is the power consumed by the light bulb? 4.00 mW 7.57 mW 15.7 mW 25.4 mW 118 mW

At what speed must a sliding rod move to produce an emf of 1.05 V in a 1.54 T field, given the rod's length is 30.3 cm? m/s

You wish to construct a solenoid with a diameter of 2.00 cm that will produce a magnetic field of 3.40 x 10-2T at its center when a current of 12.0 A is passing through the coils. You want the resistance of the coil wire to be 5.80 N. The resistivity of the wire used is 1.70 x 10-8 N •m (at 20.0°C), and you are using a wire that has a cross sectional area of 3.14 × 10-8 m2. (Note that this solenoid may not necessarily be so tightly wound that the adjacent loops of wire will touch each other. Nonetheless, you may assume that it behaves like an ideal solenoid.) Determine the following. (a) number of turns needed on the solenoid turns (b) length of the solenoid
