A strip magnet is approached to the closed wire loop. The magnet is perpendicular to the plane of the coil.

A strip magnet is approached to the closed wire loop. The magnet is perpendicular to the plane of the coil.
a) Does the magnetic flux through the coil change
b) Will there be an induction current in the loop?
c) How will your answers change if the strip magnet is removed from the wire coil?

A) the magnetic flux penetrating the circuit will increase.
B) due to the phenomenon of electromagnetic induction, an induction current will appear in the loop.
С) the magnetic flux penetrating the loop will decrease, so an induction current will appear in the loop, the direction of which is opposite to the direction of the induction current in case A).
