a circle of radius 0.75 m is placed in a uniform magnetic field of strength of 5

Question

a circle of radius 0.75 m is placed in a uniform magnetic field of strength of 5.7 T. the circle is then rotated continuously in three dimensions, so that the angle ap between the normal line to the circle and the magnetic field varies between 0 degrees and 90 degrees. The magnetic flux through the circle varies between which values? 0 Wb and 10Wb 5.7 Wb and 10 Wb 0 Wb and 17 Wb 2.8 Wb and 10 Wb a circle of radius 0.75 m is placed in a uniform magnetic field of strength of 5.7 T. the circle is then rotated continuously in three dimensions, so that the angle ap between the normal line to the circle and the magnetic field varies between 0 degrees and 90 degrees.

Explanation / Answer

flux phi = B * A * cos(theta)

phi = 5.7 * pi * 0.752

phi = 10 Wb

it varies between

0 Wb and 10Wb
