  • A current carrying loop in a uniform magnetic field will experience

    A
    force only
    B
    torque only
    C
    both torque and force
    D
    neither torque nor force

  • Torque acting on a current loop in a uniform magnetic field is equal to

    A
    `overline(P_(m)) xx overline(B)`
    B
    `overline(P_(m)) xx overline(B^(2))`
    C
    `(overline(P_(m)))/(overline(B))`
    D
    `(overline(P_(m)))/(overline(B^(2)))`

  • Asseration:The induced e.m.f. and curent will be same in two identical loops of copper and aluminium, when rotated with same speed in the same magnetic field. Reason:Induced e.m.f. is proportional to rate of change of magnetic field while induced current depends on resistance of wire.

    A
    If both asseration and reason are true and reason is the correct explanation of assertion.
    B
    If both asseration and reason are true but reason is not the correct explanation of assertion.
    C
    If assertion is true but reason is false.
    D
    If assertion is false but reason is true.

    A rectangular loop of wire is placed in a uniform magnetic field B acting normally to the plane of the loop. If a man attempt to pull it out ofthefield with velocityv as shown in figure-5.338, calculate the power required for this purpose.

    As shown in Fig. 6.26, a rectangular loop and a circular loop are moving out of a uniform magnetic field region to a field free region with a constant velocity v. In which loop do you expect the induced emf to be constant during the passage out of the field region ? The field is normal to the loops.

    The direction of induced current in the loop

    In non-uniform magnetic field in certain direction, current loop is placed

    An equilateral triangular loop ADC having some resistance is pulled with a constant velocity v out of a uniform magnetic field directed inot the paper. At time t = 0 , side DC of the loop at is at edge of the magnetic field. The induced current (i) versus time (t) graph will be as
