Toroidal Magnetic Confinement
Abstract
Toroidal magnetic confinement is a technique used in fusion energy research to confine hot plasma in a toroidal (doughnut-shaped) magnetic field. This technique is used in fusion devices known as TOKAMAKs, which are currently the most promising approach to achieving practical fusion power. The basic idea behind toroidal magnetic confinement is to use magnetic fields to contain and confine the hot plasma, which is made up of positively charged ions and negatively charged electrons. The magnetic field is designed to prevent plasma from coming into contact with the walls of the containment vessel, where it would lose its heat and energy.
