Question
A rectangular loop carrying a current i1, is situated near a long straight wire carrying a steady current i2. The wire is parallel to one of the sides of the loop and is in the plane of the loop as shown in the figure. Then the current loop will :
Options
A.move away from the wire
B.move towards the wire
C.remain stationary
D.rotate about an axis parallel to the wire
Solution
Current in A B is same as that current in straight wire so it will so it eill be attracted. CD portion will be repelled, Net force in the loop will be attractive. Force on Bc AD will be attractive. Force on BC and AD will be opposite to each other so energy will cancel out each other.
