Illustrated explanation
1Magnetic permeabilityMagnetic response and induced currents describe different effects
- Magnetic permeabilityThis term
Permeability relates flux density and magnetic field under the stated conditions. Grade name alone does not establish the complete magnetic behaviour.
- Magnetic susceptibility
The arrows represent the material’s magnetization response. Susceptibility and permeability are related but different quantities.
- Eddy current
A changing field can drive a closed current path in a conductor. Material, thickness, geometry and frequency affect the response.
Permeability and susceptibility describe material response to a magnetic field, while a changing field can induce circulating current in conductive material.
Conceptual field and current paths. No alloy’s magnetic state, shielding factor or current magnitude is assigned.
