उत्तर
The substances with all electrons paired are weakly repelled by magnetic fields. Such substances are called diamagnetic substances.
The substances with unpaired electrons are weakly attracted by the magnetic field. Such substances are called paramagnetic substances.
Examples:
| Transition metal | Lanthanoid metal | |
| Diamagnetic | Zinc | Ytterbium |
| Paramagnetic | Titanium | Cerium |
