In which orientation is the force experienced by a current-carrying conductor placed in a magnetic field (i) minimum (ii) maximum?

Explanation

Force on a current carrying conductor in magnetic field, `F=IlB sin theta`.
(i) Force F will be maximum if `sin theta=0` or `theta=0^@` or `180^@`, i.e., the linear conductor carrying current is parallel or antiparallel to the direction of magnetic field.
(ii) Force F will be maximum, if `sin theta=1` or `theta=90^@`, i.e., the linear conductor carrying current its perpendicular to the direction of uniform magnetic field.
