  • Question 1 - Select One

    Three identical circular coils A, B and C are placed coaxial (with planes parallel to each other) The coils A and C equal currents in opposite direction as shown. The coils B and C are fixed in positions and the coil A is moved towards B wiyj uniform motion then -

    Athere is no induced current in B
    Bcurrent produced by A and C in B will be equal and opposite, therefore net current in B is zero
    Cthere is an induced current in B which is in anticlockwise direction
    Dthere is an induced current in B which is in clockwise direction
