Question 2
ww-1
An aluminum bar of length /-9.00 cm slides along metal rails through a magnetic field B8=1.54 T. The switch closes at t=0 s, while the bar is at rest,
and a battery of emf bar1.03 V starts a current flowing around the loop. Solve for the terminal velocity if the battery has an internal resistance r
3.51 0 and the resistance of the rails and the bar are negligible.

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.

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.

In the figure below, the two ends of a U-shaped wire of mass m = 7.00 g and length L = 17.0 cm are immersed in mercury (which is a conductor). The wire is in a uniform field of magnitude B = 0.0860 T. A switch (unshown) is rapidly closed and then reopened, sending a pulse of current through the wire, which causes the wire to jump upward. If jump height h = 4.00 m, how much charge was in the pulse? Assume that the duration of the pulse is much less than the time of flight. Hg. Number i X L X Units X M
