  • Assertion : The net magnetic force on a current loop in a uniform magnetic field is zero but torque may or may not be zero. Reason : Torque on a current carrying coil in a magnetic field is given by vec(tau)=nI(vec(A) X vec(B)) .

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