Magnetic flux?

Question

A square loop 1.70 m on a side is placed in a magnetic field of magnitude 0.400 T. If the field makes an angle of 49.0° with the normal to the plane of the loop, find the magnetic flux through the loop.

Answer 1

Φ = BA cos θ

= 0.400 T x (1.70 m)² x cos(49.0°)

= 0.758 Wb
