"a 0.200-t magnetic field is directed perpendicular to the plane of a circular loop of radius 0.500 m. what is the magnitude of the magnetic flux through the loop? "

Magnetic flux through the loop is 0.25 Weber.

Explanation:

It is given that,

Magnetic field, B = 0.2 T

Radius of circular loop, r = 0.5 m

Magnetic field is directed perpendicular to the plane of a circular loop,

Using the formula of magnetic flux as :

So, the magnitude of the magnetic flux through the loop is 0.25 Weber. Hence, this is the required solution.

The second major reason for the difference in gravity at differentlatitudes is that the Earth's equatorial bulge (itself also caused by centrifugalforce from rotation) causes objects at the Equator to be farther from the planet's centre than objects at the poles.
