A current-carrying wire is located next to a conducting loop placed above it as shown. What is the direction of the induced current in the loop?
Select one:
A. Clockwire
B. There is no induced current
C. Counter-clockwise
D. Inpossible to tell
Explanation / Answer
1. Into the page
2. D. Inpossible to tell
a. IF current is constant then ,There is no induced current
b. if current is increases with respect to time then ,direction of the induced current in the loop is Counter-clockwise.
c. if current is decreases with respect to time then ,direction of the induced current in the loop is clockwise.
