A susceptibility of a certain magnetic material is 400 . What is the class of the magnetic material?
1 Ferromagnetic
2 Diamagnetic
3 Ferroelectric
4 Paramagnetic
Explanation:
As susceptibility is large and positive, the given material is ferromagnetic.

Assertion : Diamagnetic materials exhibit strong magnetism. Reason : Diamagnetic materials do not have permanent magnetic dipole moment.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Diamagnetism occurs when materials with paired electrons are placed in an external magnetic field. These materials, which have all their electron spins paired in opposite directions, create an induced magnetic moment in the opposite direction to the applied field. This induced magnetism is weak and temporary, and it does not involve a permanent magnetic dipole moment. So correct option is (4).

A paramagnetic liquid is taken in a \(U\) - tube and arranged so that one of its limbs is kept between pole pieces of the magnet. The liquid level in the limb:
1 Rises up
2 Goes down

Needle \({N_1},\;{N_2}\)and \({N_3}\) are made of a ferromagnetic,a paramagnetic and a diamagnetic substance respectively. A Magnet when brought close to them will
1 Attract all three of them
2 Attract \({N_1}\) strongly, \({N_2}\) weakly and repel \({N_3}\) weakly
3 Attract \({N_1}\) strongly but repel \({N_2}\) and \({N_3}\) weakly
4 Attract \({N_1}\) and \({N_2}\) strongly but repel \({N_3}\)
Explanation:
A ferromagnetic substance is strongly attracted, a paramagnetic substance is weakly attracted and a diamagnetic substance is weakly repelled by magnet.
