Question

Three magnets were dipped one by one in a heap of iron filing. The figure shows the amount of the iron filing sticking to them.

If A, B, C represent the strength of the magnets, what will be the order of strength of these magnets?

• A. A > B > C
• B. A < B < C
• C. A = B = C
• D. A < B > C

Answer 1

The correct option is A A > B > C

The stronger the magnet, the greater will be the iron filing sticking to it. The magnetic strength of a bar magnet is maximum at its ends. So, it is clear that maximum iron filings stick on the ends. As depicted from figure, the strength of the bar magnets will be in the order A > B > C.
