a positive charge Q moves along the line ab which lies in the same plane as a circular loop
Dear Student,
Since, the charge q is moving, there will be a current along the wire. According to Ampere's law, there will be a magnetic field produced due to this current along the wire. From right hand thumb rule, the magnetic field lines will be anti-clockwise and in the plane perpendicular to the wire and the circular loop.
But, the flux through the loop remains fixed and doesn't change with time hence, no current is induced in the loop.
Ans (4)
