CHARUSAT Interview Questions and Answers

Types of magnetic materials include ferromagnetic, paramagnetic, diamagnetic, and ferrimagnetic materials.

• Ferromagnetic materials: exhibit strong magnetic properties and can be easily magnetized (e.g. iron, nickel, cobalt)

• Paramagnetic materials: weakly attracted to magnetic fields and do not retain magnetization when the field is removed (e.g. aluminum, platinum)

• Diamagnetic materials: weakly repelled by magnetic fields...read more

Nanomaterials have unique properties due to their small size, high surface area to volume ratio, and quantum effects.

• Size: Nanomaterials have at least one dimension between 1-100 nanometers, leading to unique physical and chemical properties.

• Surface area to volume ratio: Nanomaterials have a high surface area compared to their volume, making them highly reactive and suitable for catalysis.

• Quantum effects: At the nanosc...read more
