Abstract
In a method and a kryomagnet for the pulsed magnetization of the kryomagnet which comprises discs stacked on top of one another, with each disc including concentric annular conductor elements arranged in axially spaced relationship and each conductor element having two contact points forming two arms between the contact points for their energization, a transport current impulse is applied to each conductor element which pulse is divided in each conductor element into first and second partial currents I1 and I2 to flow through the two arms from one of the contact points in an opposite sense to the other contact point, wherein one arm has a length of maximally 35% of the circumference of the conductor element, the transport current having a polarity such that the larger partial current flowing through the shorter arm while the transport current is increasing flows in all the conductor elements in the same direction.
