ElectroMagnetic InductionHard
Question
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
Options
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
Solution
Q will move towards P to resist the increasing magnetic flux in the loop formed due to rails R,S and conductors P,Q.
