1. A rod of mass 0.720 kg and radius 6.00 cm rests on two parallel rails (see Figure right) that are d- 12.0 cm apart and L 45.0 cm long. The rod carries a current ofI 46.0 A in the direction shown and rolls along the rails without slipping. A uniform magnetic field of magnitude 0.540 T is directed perpendicular to the rod and the rails. (a) If it starts from rest, what is the speed of the rod as...

c37. Review. A rod of mass 0.720 kg and radius 6.00 cm rests on two parallel rails (Fig. P29.37) that are d 四12.0 cm apart and L-45.0 cm long. The rod carries a L. current of 48.0 A in the direction shown. A magnetic field B of magnitude 0.240 T is directed perpendicular to the rod and the rails. The rod moves over the rails without friction. What is the acceleration of the rod? How fast is the rod moving...
This problem explores how a current-carrying wire can be accelerated by a magnetic field. You will use the ideas of magnetic flux and the EMF due to change of flux through a loop. Note that there is an involved follow-up part that will be shown once you have found the answer to Part B.A.) A conducting rod is free to slide on two parallel rails with negligible friction. At the right end of the rails, a voltage source of strength...
A horizontal current-carrying wire that is perpendicular to the plane of the paper is placed in a uniform magnetic field of magnitude 2.6 mT that is parallel to the plane of the paper and points down. At the distance 1.0 cm to the right of the wire, the total magnetic field is zero. What is the magnitude of the current in the wire if the zero field point is 0.4 cm to the left of the wire?
(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 long, straight wire carrying a current of 305 A is placed in a uniform magnetic field that has a magnitude of 6.78 × 10-3 T. The wire is perpendicular to the field. Find a point in space where the net magnetic field is zero. Locate this point by specifying its perpendicular distance from the wire.
A horizontal current-carrying wire that is perpendicular to the plane of the paper is placed in a uniform magnetic field of magnitude 3.0 mT that is parallel to the plane of the paper and points down. At the distance 1.0 cm to the right of the wire, the total magnetic field is zero. 1. What is the magnitude of the current in the wire if the zero field point is 0.4 cm to the left of the wire? Express your...
