A circular loop of radius 0.10 m is rotating in a uniform magnetic field of 0.20 T. Find the magnetic flux through the loop when the plane of the loop and the magnetic field vector are at an angle of 30 degree with each other.

Magnetic flux will be equal to  

Explanation:

It is given radius of circular loop r = 0.10 m

Area of circular loop

Magnetic field B = 0.20 T

Angle between plane of loop and magnetic field

Magnetic flux will be equal to

So magnetic flux will be equal to

concave lenses are used here. they spread the light out before it reaches the convex lens in the eye, therefore letting the image focus directly on the retina. hyperopia is known to you probably as farsightedness.

c) up is the direction the magnetic force is acting on the charge.
