MCQ
Which of the following is ferromagnetic.
- A$\text{Cu, Ag, Au}$
- ✓$\text{Fe, Co, Ni}$
- C$\text{Zn, Cd, Hg}$
- D$\text{Ca, Sr, Ba}$
✓
Answer
Correct option: B.
$\text{Fe, Co, Ni}$
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.
