1.) A loop with a resistance of 4.0 Ω is pushed to the left at a
constant speed of 2.0 m/s by a 24 N force. At the instant shown in
the figure, the loop is partially in and partially out of a uniform
magnetic field. An induced current flows from left to right through
the resistor. The length and width of the loop are 2.0 m and 1.0 m,
respectively.
What is the direction of the magnetic field?
A.) to the left
B.) into the paper
C.) Toward the top of the page
D.) out of the paper
E.) to the right
2.) Current flows around the rectangle when the rectangle
is:
I. Entering the magnetic field
II. Fully inside the magnetic field
III. Leaving the magnetic field
A.) I only
B.) I and II
C.) I and III
D.) I, II, and III
