The susceptibility of a magnetic materials is – 4.2×10^–6 . Name the type of magnetic materials it represents.

Correct option is  A) AB

Correct option is  A) F = Bqv

i. Magnetic axis: The Earth is considered to be a huge magnetic dipole. The straight line joining the two poles is called the magnetic axis. ii. Magnetic equator: A great circle in...

Correct option is: (C) 10

B = B1 + BH = μ0I + μ0H B = μ0 (I + H) B = μ0H (1 + I/H) or B = μ0 (1 + χ)H + = μH or μ = μ0...

p-type semiconductor n-type semiconductor 1. The impurity of some trivalent element like B, Al, In, etc. is mixed with semiconductor. The impurity of some pentavalent element like P, As, Sb, etc. is mixed 2....

n-type as well as p-type semiconductors are electrically neutral.

1. No.  Any slab, howsoever flat, will have roughness much larger than the inter-atomic crystal spacing (~2 to 3 Å). 2. Hence, continuous contact at the atomic level will not be possible....

Correct option is: (B) 3,4

Correct Answer - d Both are facts.
