The picture shows a loop of wire rotating in a magnetic field in a generator. Determine the direction of the current through the
load as the loop rotates from 180 to 270 degrees as shown in the picture.
A) From right to left
B) From left to right
C) There is not enough information to tell which direction the current will be in the circuit.

Answer:
T
Explanation:
= magnitude of current in each wire = 2.0 A
= length of the side of the square = 4 cm = 0.04 m
= length of the diagonal of the square =
a =
(0.04) = 0.057 m
= magnitude of magnetic field by wires at A and C
T
= magnitude of magnetic field by wire at B
T
Net magnitude of the magnetic field at D is given as
T
