Definition

The strength of a magnetic field required to bring the magnetization of a material back to zero after it has been fully magnetized.

Example

The coercivity of the magnet determines how well it can maintain its magnetization over time.

Conversation

I was reading about magnetism and came across the term coercivity.

Oh really? What does it mean exactly?

It refers to the magnetic field strength needed to demagnetize a material.

That sounds interesting! I didn't know materials had such specific properties.

Root Explanation

Coercivity is formed from "coercere" (meaning to restrain or confine) and the suffix "-ity" (meaning the state or quality of). The word refers to the quality or state of being able to restrain or compel.

Memory Tip

Think of the idea of 'restraining' ('coercere') someone, and the '-ity' indicates a state or quality. This helps you remember that coercivity is about the quality of being able to compel or restrain.
