Two identical conductors P and Q are placed on two frictionless fixed conducting rails R and S in a uniform magnetic field directed into the plane. If P is moved in the direction shown in figure with a constant speed, then rod Q
  • a)
    will be attracted towards P
  • b)
    will be repelled away from P
  • c)
    will remain stationary
  • d)
    may be repelled or attracted towards P
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Two identical conductors P and Q are placed on two frictionless fixed ...
As the conductor P moves away from Q, the area of the loop enclosed by the conductors and the rails increases. This in turn increases the flux through the loop.
EMF will be induced in such a way that the change in flux will be resisted. The induced current will cause Q to move towards P thereby reducing the area and thus the flux back.
