What is Reluctance in a Magnetic Circuit?

Click For Summary
SUMMARY

Reluctance in a magnetic circuit is the magnetic equivalent of electrical resistance, impeding the flow of magnetic flux similarly to how resistance impedes electron flow in an electric circuit. The concept is defined by the ability of materials to either facilitate or hinder the creation of magnetic flux, with air and vacuum exhibiting high reluctance and materials like soft iron demonstrating low reluctance. Understanding the properties of different materials is crucial for optimizing magnetic circuits.

Electrical resistance is due to electrons colliding with the atoms of the conductor. In a magnetic circuit reluctance is analogous to resistance in an electric circuit. Just as resistance impedes the flow of electrons in an electric circuit, reluctance impedes the flux in a magnetic circuit but how does it do this? Since flux is the magnetic field lines per unit area how does the material increase or lower the number of field lines.

It is easier to magnetize (create a magnetic flux in) some materials than others. As Wikipedia says.. "Air and vacuum have high reluctance, while easily magnetized materials such as soft iron have low reluctance".
