"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 answer would be a

heat the gas and measure the pressure
