A closed current path is made from two different circular arcs as shown in the figure below. The larger arc has radius 3.0 cm and covers one quarter of the circle, and the smaller arc has radius 1.0 cm and covers the remaining three quarters of the circle. If the current is 1.5 A going counterclockwise, what is the magnitude of the B-field at the center of the circular arcs? Express your answer to the nearest µT.

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.

Question 1: A) Dinesh studying rail guns has been suggested for launching projectiles into space without chemical rockets. A tabletop model rail gun (Figure 1.) consists of two long, parallel, horizontal rails, l= 6.80 cm apart, bridged by a bar of mass m= 8.00 g that is free to slide without friction. The rails and bar have low electric resistance, and the current is limited to a constant I = 42.0 A by a power supply that is far to the left of the figure, so it has no magnetic effect on the bar. Figure 1 shows the bar at rest at the midpoint of the rails at the moment the current is established. He wishes to find the speed with which the bar leaves the rails after being released from the midpoint of the rails (Hint: you need to draw the figure). (Mo = 4π × 10-¹T.) Jg x V₁ = = 0 m d Figure 1.

A rectangular wire loop of height h, width w, and net electrical resistance R lies in the x-y plane. As shown in the figure below, the entire region x < 0 of space is occupied by a constant, uniform magnetic field which points in the –z direction (into the page).
