Physics · Magnetic Properties of Matter
The relationship between the magnetic susceptibility (χ) and the relative magnetic permeability (μr) of a material is given by: (where μ is the permeability of the medium and μ0 is the permeability of free space)
- 1χ = 1 – μμ0
- 2χ = 1 + μrμ0
- 3χ = μr + 1
- 4χ = μμ0 – 1✓
Correct answer
χ = μμ0 – 1
