In the figure below, a steel bar sitting on two parallel metal rails, connected to each other by a resistor, is pulled to the right at a constant speed. The resistance R = 7.00 Ω, the distance between the rails is ℓ = 1.20 m, and a uniform 3.50 T magnetic field is directed into the page. At what speed (in m/s) should the bar be moved to produce a current of 0.500 A in the resistor? m/s

(a) A wire is held horizontally in a vacuum chamber, and carries a current of 1.85 μA. A proton is traveling in a direction parallel to the wire (opposite the current) with a constant speed of 2.90×104 m/s at a distance d above the wire. Ignoring the magnetic field due to the Earth, determine the value of d (in cm). cm (b) What If? At what distance d (in m) would an electron moving with the same speed as the proton move parallel to the wire? m What direction would the electron have to move? In the same direction as the proton. In the opposite direction as the proton. There is too little information to determine the direction.

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
