Question

a magnetic field of strength 0.3T is directed perpendicular to a plane circular loop of wire at radius 25cm find the magnetic flux through the area enclosed by the loop

Answer 1

Answer

the magnetic flux through the area enclosed by the loop is given

$\phi=BA$ $=B\pi r^2$

$=0.3\times3.14\times0.25\times0.25$

=0.059Wb
