1- A conducting ring of resistance R and radius l is placed in external magnetic field. Determine the charge which will pass through the ring after we give it the shape of 8? Assume that the radius of the top ring is twice smaller that the one of the bottom ring. 2- A conducting rod of length l = 10 cm is moving in external magnetic field B = 0.1 T which makes an angle α = 60◦ with the...
A conducting bar of mass m is placed on two long conducting rails a distance l apart. The rails are inclined at an angle theta with respect to the horizontal, andthe bar is able to slide on the rails with negligible friction. The bar and rails are in a uniform and constant magnetic field of magnitude B orientedperpendicular to the incline. A resistor of resistance R connects the upper ends of the rails and completes the circuit as shown. The...
4. A circular conducting loop of radius r carrying current I as shown in Fig. 4 is placed above the North pole of a cylindrical bar magnet. Everywhere on the loop, the magnetic field of the magnet has the same magnitude B and makes angle a with the vertical axis in a diverging fashion (as sketched). What is the total resultant force F produced on the loop by the magnet? Is it zero or not and why? If it is...
A bar magnet is placed at a fixed distance below and along the axis of a ring carrying 3 Amps, as shown in the figure below. At the ring, the magnetic field runs at an angle ? to the vertical. The ring has a radius of 4 meters and ? radians. Assume that l Bl 5 Tesla in the region of interest Find the magnitude of the force on the ring 4
A horizontal metal bar of mass mm and length LL is vertically suspended from two conducting wires, as shown in the figure(Figure 1). A uniform magnetic field of magnitude BB points vertically downward. Find the angle θθ the suspending wires make with the vertical when the bar carries a current II Express your answer in terms of the variables m, L, B, I Theta=
A ring of mass 2.4kg, inner radius 6.0cm, and outer radius 8.0cm is rolling (without slipping) up an inclined plane that makes an angle of theta=36.9 with the horizontal. At the moment the ring is x=2.0 m up the plane its speed is 2.8 m/s. the ring continues up the plane for some additional distance and then rolls back down. Assuming that the plane is long enough so that the ring does not roll off the top end, how far...
The figure shows a plastic ring of radius R = 50.4 cm. Two small charged beads are on the ring: Bead 1 of charge +2.06 mu C is fixed in place at the left side; bead 2 of charge +6.17 mu C can be moved along the ring. The two beads produce a net electric field of and magnitude E at the center of the ring. At what (a) positive and (b) negative value of angle theta should bead 2...
A yo-yo of mass m and radius R is placed on a horizontal surface as shown. A massless string is wrapped around an axle of radius r. The string will be pulled horizontally to the right as shown with a force of constant magnitude F. There is sufficient friction (f) between the surface and the yo-yo for the yo-yo to roll without slipping. Assume that the moment of inertia of the yo-yo about its rotation axis is approximatelyI (1/2)mR2. Draw...
