51.4 A metal wire of mass m slides without friction on two rails spaced a distance d apart, as shown in Fig. 51-4. The track lies in a vertical uniform magnetic field B (a) A constant current I flows from generator G along one rail, across the wire, and back down the other rail. Find the velocity v(t) (speed and direction) of the wire as a function of time assuming it to be at...
Chapter 28, Problem 046 in the figure, a metal wire of mass m 28.1 mg can slide with negligible friction on two horizontal parallel rails separated by distance d 2.50 cm. The track lies in a vertical uniform magnetic field of magnitude 66.2 mT. At time t 0 s, device G is connected to the rails, producing a constant current = 6.63 mA in the wire and rails (even as the wire moves). At t = 45.3 ms, what are...
6. In the figure below, a metal wire of mass m = 24.1 mg can slide with negligible friction on two horizontal parallel rails separated by distance d = 2.56 cm. The track lies in a vertical uniform magnetic field of magnitude B = 56.3 mT. At time t= 0, device G is connected to the rails, producing a constant current i = 9.13 mA in the wire and rails (even as the wire moves). At t = 61.1 ms,...
Chapter 28, Problem 046 In the figure, a metal wire of mass m26.2 mg can slide with negligible friction on two horizontal parallel rails separated by distance d = 2.13 cm. The track lies in a vertical uniform magnetic field of magnitude 58.2 mT. At time t-0 s, device G is connected to the rails, producing a constant current, = 7.69 mA in the wire and rails (even as the wire m oves). At t = 73.1 ms, what are...
A conducting bar slides without friction on two parallel horizontal rails that are 50 cm apart and connected by a wire at one end. The resistance of the bar and the rails is constant and equal to 0.10 0. A uniform magnetic field is perpendicular to the plane of the rails. A 0.080-N force parallel to the rails is required to keep the bar moving at a constant speed of 0.50 m/s. What is the magnitude of the magnetic field...

Problem 6. A conducting rod of mass 50 grams slides without friction on a pair of conducting horizontal rails spaced 0.750 m apart. A steady current of 85.0 A exists in the rails and bar as shown. The rails and bar are in a uniform 1.35 T magnetic field directed as shown. (a) What is the magnitude and direction of the acceleration of the rod? (b) If the rod starts from rest and reaches a speed of 150 m/s when...
(Magnetic Force on a Wire) A horizontal,
current-carrying wire of mass m = 40.0 g is free to slide without
friction along two vertical conducting rails spaced l = 80.0 cm
apart as in Figure. A uniform magnetic field of B = 1.20 T is
directed into the plane of the drawing. What magnitude and
direction (to the right or to the left) must the current have if
the force exerted by the magnetic field on the wire is just...
A 0.100-kg metal rod carrying a current of 15.0 A glides on two horizontal rails 0.550 m apart and 2.0 m long, (a) If the coefficient of kinetic friction between the rod and rails is 0.120, what vertical magnetic field is required to keep the rod moving at a constant speed? (b) If the friction between the rod and rail is reduced zero, the rod will accelerate. If the rod starts from rest at the one end of the rails,...
A 0.300-kg metal rod carrying a current of 12.0 A glides on two horizontal rails 0.590 m apart and 2.0 m long. (a) If the coefficient of kinetic friction between the rod and rails is 0.160, what vertical magnetic field is required to keep the rod moving at a constant speed? (b) If the friction between the rod and rail is reduced zero, the rod will accelerate. If the rod starts from rest at the one end of the rails,...
