For each part, determine whether the magnetic flux Φ through the loop due to Ii is into the page, out of the page or zero, and whether the current 12 induced in the loop is clockwise, counterclockwise or zero. a) I1 is constant to the left and the loop is moving toward the wireΦ: into page/out of page/zero I2: clockwise/counterclockwise/zero b) I1 is increasing to the right Φ: into...
A square loop of wire with a small resistance is moved with constant speed from a field free region into a region of uniform B field (B is constant in time) and then back into a field free region to the left. The self inductance of the loop is negligible. When entering the field the coil experiences a magnetic force to the left. When leaving the field the coil experiences a magnetic force to the right. Upon entering the field,...

Faraday’s Law and Induced EMF The figure displays a rectangular loop of wire with sides x and y placed in a region where a uniform magnetic field ! exists. The resistance of the loop is R. Initially the field is perpendicular to the plane of the loop and is directed out of the page. The loop can rotate about either the vertical or horizontal axis, passing through the midpoints of the opposite sides, as shown. 1. Which of the following...
A square loop of wire with side length 10 cm is moving to the right with constant speed of 16 m/s. The loop has total resistance of 0.8 ohms. It begins in a region with no magnetic field, then enters a region of magnetic field (wider than 10 cm) with a strength of 0.5 T pointing into the page. Finally it leaves the field. 21) While entering the field what is the direction of the induced current as seen from above...
Suppose that a copper wire loop is placed in the magnetic field of a solenoid. For each situation below, determine (i) whether or not there is a current induced in the wire loop. If a current is induced, (ii) give its direction according to an observer looking at the setup from the right, (iii) state whether the loop is attracted towards or repelled from the solenoid, and (iv) state whether the force exerted on the loop tends to increase or...
