      A tokamak is a device
        which uses a powerful magnetic field to confine plasma in the
        shape of a torus.
        The tokamak is one of several types of magnetic confinement
        devices being developed to produce controlled thermonuclear
        fusion power.
        As of 2020, it is the leading candidate for a practical fusion
        reactor
