The relation between total magnetic field (B), magnetic intensity ( H ) , permeability of free space ( ₀ ) and susceptibility ( ) is
Options
- AH B = ₀(1+ )
- BB H = ₀(1+ )
- CH B = ₀( -1)
- DB H = ₀(1- )
Correct answer
B. B H = ₀(1+ )
Step-by-step solution
The net magnetic field, B has two contributions: - Contribution from external factors ( ( B ₀ ) ). For example, the current-carrying wire will generate its own magnetic field. This is called Magnetic intensity (H). - The contribution due to the specific nature of the material ( (B_m ) ). For instance, some materials magnetize in the direction of the magnetic field and some against it. This is called magnetization (M). - It is influenced by external factor ( H ). This can be seen from the relation ( M= H ) Also, (B_
