A long, straight wire carries a current and lies in the plane of a rectangular loops of wire, as shown in the figure. Determine the maximum emf, |epsilon|, induced in the loop by the magnetic field created by the current in the straight wire.
The long, straight wire shown in the figure a carries constant current I. A metal bar with length L is moving at constant velocity v, as shown in the figure. Point a is a distance d from the wire. Part A Calculate the emf induced in the bar. Part B Which point, a or b, is at higher potential? Part C If the bar is replaced by a rectangular wire loop of resistance R (the figure b), what is the magnitude of the current induced in...
A long straight wire is in the same plane as a rectangular, conducting loop.

A loop of wire with radius R lies in the xy-plane and carries a time varying current I(t) I, sin(ot). A smaller loop of wire with radius a lies in the xy-plane at the center of the larger loop. Assume that radius of the smaller loop is much smaller that the radius of the larger loop, a<<lR a) (10 points) At the center of the large loop calculate the magnitude and direction of the magnetic field B(t) due to the...
Problem 2 (Current through Loop) A rectangular loop of dimensions / and w moves with a constant velocity v away from an infinitely long straight wire carrying a current I in the plane of the loop, as shown in Figure 10.9.6. Let the total resistance of the loop be R. What is the current in the loop at the instant the near side is a distance r from the wire?

A straight wire carries a steady current I as shown. A metal bar
is in contact with a pair of rails and is moving upward with a
velocity of magnitude v. The direction of circulation of the
induced current in the metal bar is:- No current circulates- Left to right- Right to left
A metal loop moves at constant velocity toward a long wire carrying a steady current I, as shown in the figure below. The current induced in the loop is directed clockwise. counterclockwise. zero. first clockwise, then counterclockwise. first counterclockwise, then clockwise.
