Abstract
Magnetic fields are applied to the examination subject, and the deflection of the atomic nuclei of the examination subject from their state of equilibrium by means of a high frequency magnetic excitation pulse is detected. There is at least one gradient coil for the purpose of generating a linear magnetic field gradient. The gradient coil is connected, in series with an additional inductance, to a current source. Connected in series with the gradient coil is a first switch. Connected in parallel with the series of connection of gradient coil and first switch is a second switch actuatable to open condition approximately simultaneously with the closure of the first switch.
