FAQs on Magnetic Properties of Materials (Diamagnetism,Paramagnetism & Ferromagnetism) Video Lecture - Physics Class 12 - NEET

1. What is diamagnetism?
Ans. Diamagnetism is a property exhibited by certain materials that causes them to create a weak magnetic field in the opposite direction when exposed to an external magnetic field. This results in the material being repelled by the magnetic field.
2. What is paramagnetism?
Ans. Paramagnetism is a property exhibited by certain materials that causes them to create a weak magnetic field in the same direction when exposed to an external magnetic field. This results in the material being attracted to the magnetic field.
3. What is ferromagnetism?
Ans. Ferromagnetism is a property exhibited by certain materials that causes them to retain a strong magnetic field even after the external magnetic field is removed. These materials can be permanently magnetized and are commonly used in magnets.
4. What are some examples of diamagnetic materials?
Ans. Some examples of diamagnetic materials include bismuth, copper, silver, and gold. These materials have all their electrons paired up, resulting in a canceling effect of their magnetic moments.
5. What are some examples of paramagnetic materials?
Ans. Some examples of paramagnetic materials include oxygen, aluminum, platinum, and chromium. These materials have unpaired electrons, causing their magnetic moments to align with the external magnetic field.
