Question

A rectangular loop moves into a region where the magnetic field points out of the page. What happens to the flux through the loop?

पर्याय

• It disappears before the loop enters the field.

• It increases because more magnetic field lines pass through the loop.

• It decreases because fewer magnetic field lines pass through the loop.

• It does not change because the loop is rectangular.

Answer 1

As the rectangular loop enters the field region, more field lines pass through it. Its magnetic flux therefore increases.
