Question 3

Three magnets A, B and C were dipped one by one in a heap of iron filing. Fig. shows the amount of the iron filing sticking to them.

The strength of these magnets will be

(a) A > B > C

(b) A < B < C

(c) A = B = C

(d) A < B > C

Solution

Option (a) is the correct answer.

Stronger the magnet, greater will be the iron filing sticking on them. The magnetic strength of a bar magnet will be maximum at its ends. So from the figure, it is clear that the iron filings stuck on A is the most and C is the least. So the strength of the bar magnets will be in the order A>B>C.
