Question
When current flows clockwise in a loop, the polarity of its face isA East B South C West D North
Solution
The question seems to be about the right-hand rule in electromagnetism. According to this rule, if you point the thumb of your right hand in the direction of the conventional current (which is the direction in which positive charges would move), then your fingers will curl in the direction of the magnetic field.
So, if the current is flowing clockwise when you are looking at the loop, the magnetic field lines will be directed into the loop. This is similar to the south pole of a magnet. Therefore, the correct answer is B) South.
