"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?"

Respuesta :

Answer:

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, [tex]\theta'=90[/tex]

Using the formula of magnetic flux as :

[tex]\phi=BA\ cos\theta[/tex]

[tex]\phi=BA\ cos(90-\theta)[/tex]

[tex]\phi=BA\ sin(90)[/tex]

[tex]\phi=0.2\times \pi (0.2)^2[/tex]

[tex]\phi=0.025\ Wb[/tex]

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