A rectangular closed loop is placed near a long current I carrying wire, as shown in figure.
A. If I is increased, induced current in loop is anticlockwise
B. If I is increased, the wire will repel the loop.
C. If loop is moved away from the wire induced current in the loop is anticlockwise
D. If loop is moved away from the wire, wire will attract the loop.
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A, B and D only
(A) If I is increased, the induced magnetic field will appose the increase in B, creating a current in the loop in anticlockwise direction.
(B) When I increases, the magnetic interaction between the wire and the loop creates a repulsive force.
(D) When the loop is moved away, the metal inductance decreases, and the wire exert an attractive force to oppose the motion of the loop.
