Question

A student places some iron fillings around a magnet. The iron fillings arrange

themselves as shown in image.

The student labelled four different regions around the magnet. Where would be the magnetic

be the strongest?

a) P

b) Q

c) S

d) R​

Answer 1

Answer:

a) p

Explanation:

I hope right answer

Answer 2

The magnetic effect will be the strongest at (d) R.

• A magnet is a substance that can attract magnetic materials and has magnetic properties.
• Iron filings when paced around a bar magnet (as shown in the image) get attracted to it and form a pattern that resembles magnetic field lines around a bar magnet.
• The effect of magnetic force at a point is directly proportional to the concentration of iron filings.
• In the figure, we can see that most of the iron filings are attached to the poles. Hence at point R, the magnetic field is strongest.
