ElectroMagnetic InductionHard
Question
In a cylindrical region uniform magnetic field which is perpendicular to the plane of the figure is increasing with time and a conducting rod PQ is placed in the region. If C is the centre of the circle then
Options
A.P will be at higher potential than Q.
B.Q will be at higher potential than P.
C.Both P and Q will be equipotential.
D.no emf will be developed across rod as it is not crossing / cutting any line of force.
Solution
If the circuit Q C P containing rod PQ is completed then the direction of induced current will be from Q to C to P hence Q will be at higher potential than P.
