Question

Choose the correct match

A. Ferromagnetic	(a) water
B. Diamagnetic	(b) cobalt
C. Paramagnetic	(c) chromium

• A. A-b, B-c, C-a
• B. A-c, B-a, C-b
• C. A-b, B-a, C-c
• D. A-a, B-a, C-b

Answer 1

The correct option is C

A-b, B-a, C-c

1. Diamagnetic substances exhibit practically no magnetic properties. However, in a powerful magnetic field, they are feebly repelled by magnets. Example: Antimony, gold, bismuth, lead, water, etc.
2. Paramagnetic substances get feebly magnetized in a powerful magnetic field and are feebly attracted by powerful magnets. Example: Platinum, chromium, aluminum, etc.
3. Ferromagnetic substances are easily magnetized by an external magnetic field and are strongly attracted by magnets. They are used to make artificial magnets. Example: Iron, nickel, cobalt, etc.

Thus, the correct option is (C) A-b, B-a, C-c
