A rectangular wire loop is at rest in a uniform magnetic field B of magnitude 2

Question

A rectangular wire loop is at rest in a uniform magnetic field B of magnitude 2 T that is directed out of the page. The loop measures 5 cm by 8 cm, and the plane of the loop is perpendicular to the field, as shown above. The total magnetic flux through the loop is zero 2 x 10-3 T•m^2 8 x 10-3 T•m^2 2 x 10-1 T•m^2 8 x 10-1 T•m^2 A rectangular wire loop is at rest in a uniform magnetic field B of magnitude 2 T that is directed out of the page. The loop measures 5 cm by 8 cm, and the plane of the loop is perpendicular to the field, as shown above. The total magnetic flux through the loop is zero 2 x 10-3 T?m^2 8 x 10-3 T?m^2 2 x 10-1 T?m^2 8 x 10-1 T?m^2

Explanation / Answer

Given Magnitude of field , B = 2T Area of the loop , A = 0.05 m * 0.08 m = 0.004 m^2 Total magnetic flux is , = BA                                       = 2T * 0.004 m^2                                    = 8 *10^-3 Tm^2 option 2 is correct
