Source sentences:
text: If the magnetic field in the plasma is not stationary, either because the plasma as a whole is transient or because the fields are periodic (radio-frequency heating), the rate of change of the magnetic field with time ( B ˙ {\displaystyle {\dot {B}}} , read "B-dot") can be measured locally with a loop or coil of wire.
