Question
A rectangular loop of wire of length a =
b = 0.051 m, and resistance 0.079 Q, is located in the
0.086 m, width
X-y plane, as shown in the figure below. There is
uniform magnetic field B = 1.47 T in the z direction.
a. What is the magnetic flux through the loop?
b. The magnetic field increases to B = 3.12 T in
%3D
%3D
0.82 s. Is an electric current induced in the
loop, and if so, what is it? Specify whether the
current flows clockwise or counterclockwise.
C. Now, with the magnetic field held constant at B
= 3.12 T, the rectangle starts moving in the x
direction with a speed of 1.9 m /s. Is an electric
current induced in the loop, and if so, what is it?
Specify whether the current flows clockwise or
%3D
counterclockwise.
