Problem 5P
A 12.0-cm-diameter loop of wire is initially oriented perpendicular to a 1.5-T magnetic field. The loop is rotated so that its plane is parallel to the field direction in 0.20 s. What is the average induced emf in the loop?
ANSWER:
Solution 5P:
Step 1 of 2:-
Here we have to calculate the average induced emf in the loop.
The diameter of the loop is 12 cm, which is .
The area of the loop is,
.
The magnetic field is,
.
The direction of the magnetic field with respect to the area was .
It took 20 s to make the angle parallel or .
