At least one 1 in 4 white dwarfs will end its life as a magnetic star. At the end of their life, most stars shrink in size to the dimension of a small planet, an object called a "white dwarf," a late stage of stellar evolution.

When the density of the hot, ionized gas (known as a plasma) in a tokamak exceeds a certain limit, it usually leads to a rapid loss of heat and plasma currents. The currents are required to confine the plasma. Such events ...
