Thank ya

The sequence below shows a rectangular loop passing from left to right from a region of zero magnetic field (indicated by a white background) into a region of constant non-zero magnetic field (indicated by a tan background) then back out again. (A) B (c) (D) (E) In which part of the sequence is the magnetic flux through the loop decreasing? (B), when the loop is entering the magnetic field O (D), when the loop is leaving the magnetic field (E), when the loop is moving from left to right and moving away from the magnetic field O (C), when the loop is moving from left to right inside the magnetic field (A), when the loop is moving from left to right and approaching the magnetic field
