Answer 1

Answer:

We can determine the north and south pole of an electromagnet with the help of a magnetised iron bar.

Answer 2

Answer:

Take a magnetic compass and place it close to but not touching your magnet. Watch carefully at where the compass needle points. The point that normally points to the north pole of Earth should point to one end of the magnet. That end is actually the South pole of the magnet.
