प्रश्न
Explain the significance of a radial magnetic field when a current-carrying coil is kept in it.

उत्तर
The uniform radial magnetic field keeps the plane of the coil always parallel to the direction of the magnetic field. That is, the angle between the plane of the coil and the magnetic field is zero in all the orientation of the coil.
