Definition

A special type of chamber shaped like a doughnut that is used in research to create energy through nuclear fusion by heating and holding a gas called plasma with magnetic fields.

Example

Scientists are experimenting with a tokamak to develop new energy sources.

Conversation

Have you ever heard of a tokamak?

Yeah, I think it's that device used for fusion research, right?

Exactly! It's fascinating how it uses magnetic fields to confine plasma.

Totally! I read that it's crucial for developing clean energy.

Root Explanation

Tokamak is derived from the Russian acronym "ТОКАМАК" (pronounced 'tokamak'), which stands for "toroidal chamber with magnetic coils". The term combines "toroidal" (meaning shaped like a torus or doughnut) and "magnetic" (referring to the magnetic fields used to confine plasma). Thus, a tokamak is a device designed to confine plasma in a toroidal shape using magnetic fields for the purpose of nuclear fusion.

Memory Tip

Imagine a doughnut-shaped chamber ('toroidal') that uses magnets ('magnetic') to hold hot plasma inside — that's what a tokamak does.
