The figure on the right shows a sequence of a rectangular loop passing from left to right through a region of constant magnetic field. The field points into the page and perpendicular to the plane of the loop. In which one of the sequences is the magnetic flux through the loop decreasing? (A) from left to night approaching the magnetic field (B) entering the magnetic field (C) inside the magnetic field (D) leaving the magnetic field (E) from left to right moving away from the magnetic field

Solution

The magnetic flux is decreasing in the case \'D\' : leaving the magnetic field.
This is because the area of the loop through the magnetic field is decreasing only in D.

A) flux zero (constant)

B) flux increasing

C) flux maximum (constant)

D) flux decreasing

E) flux zero (constant)
