Which of the following material when placed in an external magnetic field behaves as shown in the figure?

The correct answer is option 2) i.e. Diamagnetic

CONCEPT:

• Diamagnetic substance: Diamagnetic substances are those that are capable of weakly getting magnetized when placed in an external magnetic field.
  • ​The magnetization takes place in a direction that is opposite to the external magnetic field. 

​

• When an external magnetic field is applied, the dipoles are induced in the diamagnetic materials that arrange themselves in such a way that they start opposing the external magnetic field.
• The atoms of diamagnetic substances have paired electrons.
• A few examples of diamagnetic substances are Copper, Zinc, Bismuth, Silver, and Gold.

EXPLANATION:

• Diamagnetic materials have the property of opposing the external magnetic field and do not allow it to pass through them.
• The given figure shows a diamagnetic specimen placed in an external magnetic field.

Additional Information

• Paramagnetic substances: Paramagnetic substances are those substances that get weakly magnetized with the influence of an external magnetic field.
• Ferromagnetic materials: Ferromagnetic substances are those substances that get strongly magnetized when placed in an external magnetic field.
