What is the Coercivity of a Magnetic Field?

Coercivity, often referred to as coercive force, is a fundamental property of magnetic materials that measures the ability of a material to resist becoming demagnetised when an external magnetic field is applied and then removed.

What is a Closed Circuit?

A closed magnetic circuit refers to a path or loop that allows a magnetic field to flow through a continuous route without any interruption or air gaps.

What is a Bar Magnet?

A bar magnet is a permanent magnet and has a magnetic length that is bigger than its diameter. A bar magnet normally has a north pole and a south pole at opposite ends of the bar.

What Does Axially Magnetised Mean?

Axially magnetised refers to a specific orientation of magnetisation in which the magnetic poles are located at the opposite ends, or faces, of the magnet.

What Does Anisotropic Mean?

Anisotropic is a term used to describe the directional dependence of magnetic properties in magnets. In anisotropic magnets, the magnetic properties, such as magnetic strength and orientation, are not the same in all directions.

What is an Air Gap?

An ‘air gap’ is the bit between a magnet and an attracted object or between two magnets attracted to each other. It is often described as a break in the magnetic circuit which the magnetism has to jump through to continue the circuit.
