FQA of MAGNETIC POLES
- Jun 09, 2019-
What are magnetic poles?
Magnetic poles are the surfaces from which the invisible lines of magnetic flux emanate and connect on return to the magnet.
What are the standard definitions of “North” and “South” pole?
The north pole is defined as the pole of a magnet that, when free to rotate, seeks the north pole of the earth. In other words, a magnet's north pole will seek the earth's north pole. Similarly, the south pole of a magnet seeks the south pole of the earth.
Can a particular pole be identified?
Yes, the north or south pole of a magnet can be marked if specified.
How can you tell which is the North Pole if it’s not marked?
You can't tell by looking. You can tell by placing a compass close to the magnet. The end of the needle that normally points toward the north pole of the earth would point to the south pole of the magnet.
