Question

6. What do you understand by the magnetic axis of a bar magnet?​

Answer 1

Answer:

: the straight line joining the two poles of a magnet (as the magnetic poles of the earth)

You can use a plotting compass or iron filings to detect a magnetic field:

put a piece of paper over a magnet (this stops the iron filings sticking to the magnet)

sprinkle iron filings onto the paper.

gently tap the paper to spread the filings out.

observe and record the results.
