The figure on the right shows two parallel loops of wire having a common ât axis. The smaller loop (radius r) is above the larger loop (radius R), by a distance x > R. Assume the magnetic field due to the current i in the larger loop is basically constant over the area of the smaller loop and equal to the value on the axis. 10. Suppose the smaller loop moves away from the larger loop at constant speed: x(t) = xo + Væt, with v, > 0, xo > 0. a) assuming its resistance is 12. Ignore any retardation effect. Find the magnitude and direction of the induced current in the smaller loop b) Is there a time t where the induced current is 0? Explain carefully your answer, using thAux of B.
Let's add a battery to the usual sliding rod set-up: B is uniform sliding rod The whole circuit is lying horizontally on the ground. The rod starts at rest, and accelerates due to the magnetic force on it. After a while, you discover that its velocity stops changing. What is the value of the final speed (in m/s) of the rod? The magnetic field is 8.27T, the battery has an emf of 6.03V, the resistor is 4.54 ohm, and the distance between the two parallel rails is 4.56m. Hint: Pay attention to the magnitude of the magnetic force on the sliding rod. Rewrite the circuit in the usual way: by replacing the sliding rod with a battery of emf=BvL; then apply Kirchhoff's loop rule.

The wire has a 0.85 mΩ resistance and a mass of 4.4 g . Ignore the resistance of the rails. The power supply is switched on. What is the magnitude of the force on the wire? What will be the wire's speed after it has slid a distance of 8.0 cm ?

An electrically conductive rod is moving through a uniform magnetic flux at a constant velocity at right angles, as shown by its cross-section in the diagram. The velocity is in the x-direction, the rod is of length 150 mm along z, and the magnetic flux density is 0.2 T in the positive y-direction. Speed If the potential difference (voltage) across the ends of the rod is 5.8 Volts, what is the magnitude of the velocity? m/s Not perpendicular If the rod is passing through the flux with its axis not at right angles what can you be sure of? The speed to generate 5.8 V would have to be smaller. • The speed to generate 5.8 V would have to be bigger. The speed to generate 5.8 V would be the same.
Suppose you have a long straight wire AB, carrying a current in the direction shown in the figure. Below this wire is a rectangular loop 20 cm long and 5 cm wide, carrying a current of equal magnitude to the wire, where the long sides are parallel to the wire. The wire and the loop both have a linear density equal to 0.0125 kg/m. The separation between the upper long side of the loop and the wire is 1 cm. What would happen if you move the loop just a little bit down?
