Definition

A type of magnetism that occurs when a material creates a weak magnetic field in the opposite direction of an external magnetic field, causing it to be repelled by the magnet.

Example

Copper exhibits diamagnetism, meaning it is repelled by magnetic fields.

Conversation

Have you ever heard about diamagnetism?

I think so, but I don't really understand what it is.

It's basically a weak form of magnetism that appears only with an external magnetic field.

That’s interesting! I didn’t know magnetism could be so complex.

Root Explanation

Diamagnetism → It is formed from "dia-" (meaning through or across) and "magnetism" (from Greek "magnetis" meaning magnet). The term describes a phenomenon where materials are repelled by a magnetic field, effectively acting across the influence of magnetism.

Memory Tip

Think of 'dia-' meaning 'through' and 'magnetism' referring to the magnetic force — this helps you remember that diamagnetism is the effect of materials acting against magnetic fields.
