Asquare loop of wire consisting of a single turn is perpendicular to a uniform magnetic field. the square loop is then re-formed into a circular loop, which also consists of a single turn and is also perpendicular to the same magnetic field. the magnetic flux that passes through the square loop is 6.68 × 10-3 wb. what is the flux that passes through the circular loop?

0.0085 Wb

Explanation:

a = Side of square

r = Radius of circle

= Magnetic flux through square loop =

Magnetic flux is given by

For square

The length of the square will be equal to the circumference of the circle

For circle

The flux that passes through the circular loop is 0.0085 Wb

car a and b are moving in opposite directions

plz mark.me the brainliest i rlly need this kind of yours in exchange
