MCQ
Which of the following is ferromagnetic.
- ACu, Ag, Au
- BFe, Co, Ni
- CZn, Cd, Hg
- DCa, Sr, Ba
✓
Answer
- Fe, Co, Ni
Explanation:
Ferromagnetic substances are those which get strongly magnetized in the presence of a magnetic field.
These substances have domains that get aligned in the magnetic field, thus increasing their strength.
These are strongly attracted by a magnet.
Examples include iron, cobalt, nickel, etc.
