Question

Which of the following substances have a tendency to move
from stronger to the weaker part of an external magnetic
field ?
(A) Paramagnetic
(B) Diamagnetic
(C) Ferromagnetic
(D) None of the above​

Answer 1

Answer:

(B) is correct option.

Explanation:

Diamagnetic substance has a tendency to be repelled by magnetic field

Answer 2

Answer:

Diamagnetic substances have the tendency to move from the stronger to the weaker part of an external magnetic field i.e.(B).

Explanation:

• Paramagnetic substances -These are the materials that get weakly magnetized when placed in an external magnetic field. They have a tendency to move from a region of the weak magnetic field to a strong magnetic field i.e.they get weakly attracted by magnets.
• Diamagnetic substances-These are the materials that have the tendency to move from the stronger to the weaker part of the external magnetic field.i.e.they get repelled by the magnet.
• Ferromagnetic substances-These are the materials that get strongly magnetized when placed in the external magnetic field. They have the tendency to move from a region of the weak magnetic field to a strong magnetic field.i.e.they get strongly attracted to a magnet.

Hence, the correct answer among the given option is diamagnetism i.e.option(B).
