Question

explain the two methods of plotting a magnetic field of a permanent magnet.

Answer 1

Explanation:

Three methods of producing magnetic fields are as follows:

(a) Magnetic field can be produced by placing a permanent magnet or a horse-shoe magnet at the place, where magnetic field is required. (b) Magnetic field is produced around a current carrying straight conductor or a current carrying coil

Answer 2

Answer:

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
