Homework Answers
If the loop is released from rest in the magnetic field, there would be no force acting on the loop. The right end points upwards and the left end points downwards. There is net torque acting on the loop. As a result, it rotates in a counterclockwise direction.
Hence the answer is rotates counterclockwise.

A bar magnet is released from rest some height above the center of a loop wire standing flat on a table, as shown in the figure below. The wire has no net charge and no initial current is flowing in it. The magnitude of the acceleration of the falling magnet will be O slightly larger than 9.8 m/s2 much larger than 9.8 m/s2 exactly 9.8 m/s2 exactly 4.9 m/s2 smaller than 9.8 m/s2 S N

A rectangular loop of wire with dimensions and w is released from rest at time t = 0 from a region with zero magnetic field into a region with uniform magnetic field Bo pointing into the page. At t=0, the upper edge of the loop is in the zero field region and the lower edge is in the uniform field region as shown in the figure below. The loop has mass m and the acceleration due to gravity is g...
A bead with a hole through it slides on a wire track. The wire is threaded through the hole in the bead, and the bead slides without friction around a loop-the-loop (see figure below). The bead is released from rest at a height h = 3.90R.

A roller-coaster car shown in the figure on the right is released from rest from a height h and then moves freely with negligible friction. The roller-coaster track includes a circular loop of radius R in a vertical plane. a. First suppose the car barely makes it around the loop; at the top of the loop, the riders are upside down and feel weightless. Find the required height h of the release point above the bottom of the loop in...
