Practice Class 12 Physics Important Questions

Question: The susceptibility of a magnetic material is 1.9 × 10-5. Name the type of magnetic materials it represents. (Delhi 2011)
Answer:
It represents Paramagnetic substance

Question: Where on the surface of Earth is the angle of dip zero? (All India 2011)
Answer:
At the magnetic equator, the angle of dip is 0°.

Question: The horizontal component of the earth’s magnetic field at a place is B and angle of dip is 60°. What is the value of vertical component of earth’s magnetic field at equator? (Delhi 2011)
Answer:
BH = B cos δ
BV = BH tan δ = B tan 60° = B × √3 = √3B
∴ At equator, BV = 0 (zero).

Question: What are permanent magnets? Give one example. (Delhi 2013)
Answer:
Substances which at room temperature retain their ferromagnetic property for a long period of time are called permanent magnets.
Example: Steel, alinco
