Interesting Facts
- Neodymium is not found free in nature, hence it is not a native metal.
- Neodymium metal found in minerals like Monazite and Bastnaesite.
- At times Terbium metal acts same as Calcium.
- Terbium metal closely similar to Lanthanum metal.

Uses & Benefits
- Neodymium-Iron-boron alloy is used to make permanent magnets.
- It is used in microphones, Mp3 player, loudspeakers, mobile phones, etc.
- Terbium salts are used in optical devices like laser devices.
-
Terbium’s alloy lengthens and shortens the magnetic field and this effect forms loudspeaker.
