magnetic bottle
A scientist observes a glowing plasma contained within a magnetic bottle in the laboratory.
Noun: A magnetic bottle is a device or configuration of magnetic fields designed to confine and contain a plasma (a hot, ionized gas) to prevent it from touching the walls of a container. This is essential for achieving controlled thermonuclear fusion reactions, such as those researched for potential energy production.
The term is used specifically in the context of plasma physics and fusion energy research. It describes the magnetic confinement principle, not a physical container.
- Scientists are testing a new magnetic bottle design to improve plasma stability.
- Containing the ultra-hot plasma within a magnetic bottle is a major challenge for fusion reactors.
- The tokamak is a type of magnetic bottle shaped like a torus (doughnut).
- Conceptual Use: The term can be used metaphorically to describe any non-physical, magnetic-based containment system.
- The experimental device acts as a magnetic bottle, holding the fusion fuel in place.
- Magnetic Confinement: The general principle of using magnetic fields to trap plasma.
- Tokamak: A specific, toroidal (doughnut-shaped) design of a magnetic bottle.
- Stellarator: Another type of magnetic bottle with a twisted, complex magnetic field geometry.
- Plasma Confinement: The broader goal achieved by a magnetic bottle.
- Magnetic trap
- Magnetic confinement device
(This is a technical term with no common idioms. Its usage is literal and scientific.)
