Question

Formula for calculating intensity of magnetic from magnetic susceptibility and magnetic field

Answer 1

hey mate here is your answer..

The magnetic susceptibility of silicon is −0.4 × 10−5. Calculate the flux density and magnetic moment per unit volume when magnetic field of intensity 5 × 105 A/m is applied.

sol: Given: χ = –0.4 × 10‒5

H = 5 × 105 A /m

B = ? and M = ?

B = μ0(H + M) = μ0 H(1 + χ)

= 4π × 10‒7 × 5 × 105 [1 – 0.4 × 10‒5] = 4π × 5 × 10‒2 × 0.9996 = 0.62 Wb/m2

M = χH = –0.4 × 10–5 × 5 × 105 = –2.0 A/m.

hope it's helpful for you...

Answer 2

Answer:

In electromagnetism, the magnetic susceptibility (Latin: susceptibilis, "receptive"; denoted χ) is a measure of how much a material will become magnetized in an applied magnetic field. Mathematically, it is the ratio of magnetization M (magnetic moment per unit volume) to the applied magnetizing field intensity H. This allows a simple classification of most materials' response to an applied magnetic field into two categories: an alignment with the magnetic field, χ>0, called paramagnetism, or an alignment against the field, χ<0, called diamagnetism.
