A) the plane of coil is parallel to the magnetic field
B) the plane of coil is perpendicular to the magnetic field
C) the plane of coil is at an angle of \[60{}^\circ \] with the magnetic field
D) the plane of coil is at an angle of \[120{}^\circ \] with the magnetic field
Correct Answer: A
Solution :
(a) the plane of coil is parallel to the magnetic field Magnetic flux, \[\phi =BA\,\,\cos \,\theta \] \[\phi =0\] when \[\theta =0{}^\circ \], i.e., plane of coil is parallel to the magnetic field.
