At which angle between magnetic flux and the vector area is the flux zero?

مقناطیسی بہاؤ اور ویکٹر ایریا کے درمیان کس زاویہ پر بہاؤ صفر ہے؟

0 degrees

45 degrees

90 degrees

None of these

Explanation

Magnetic flux ( $Phi$ ) is given by $Phi = B cdot A cdot costheta$ , where $theta$ is the angle between the magnetic field ( $B$ ) and the vector area ( $A$ ).

When $theta = 90^circ$ , $cos 90^circ = 0$ , so the flux becomes zero.
