Question

A flat coil is in a uniform magnetic field. The magnetic flux through the coil is greatest when the plane of its area is

A. perpendicular to the magnetic field.

B. parallel to the magnetic field.

C. at 45� with the magnetic field.

Answer 1

The magnetic flux through a flat coil is greatest when the plane of its area is perpendicular to the magnetic field.

Step-by-step explanation:

The magnetic flux through a flat coil is greatest when the plane of its area is perpendicular to the magnetic field.

When the coil is in a position such that its normal vector makes an angle with the magnetic field, the magnetic flux through the coil is reduced.

Therefore, the magnetic flux is maximized when the coil is oriented perpendicular to the magnetic field.
