Question

We insert (from the top) the south pole of a bar magnet into a flat horizontally laying conducting rectangular ring. As seen from

the top (re, top-down view), what is the direction of the current induced in the ring? downward
upward
DYG
counter-clockwise
• dis clockwise

Answer 1

When a south pole of a bar magnet is inserted in a conducting rectangular ring from the top, the resulting induced current will flow in a counter-clockwise direction, as inferred from Faraday's law of electromagnetic induction.

Step-by-step explanation:

According to Faraday's law of electromagnetic induction, the direction of the induced current in the conducting rectangular ring would be such as to oppose the change in the magnetic field. As such, if we are inserting the south pole of a magnet into the ring from the top, the ring would try to repel the intruding south pole by setting up its own south pole on the top side, and to do so the current should flow in a counter-clockwise direction when viewed from the top.
