β¦ Synopsis
In many technical devices an a.c.-supplied "ptimary" magnetic field induces eddy-current flow in a "secondary" armature. Exact calczclation of the overall field distribution is diflcult, hence, the secondary jield is often neglected in practice and only an estimate of the interaction is obtained. This paper outlines a general solution of the problem with both fields taken into account, and the specific model discussed shows how to proceed in more complicated cases.

## Abstract We describe a technique for measuring the time dependence and field distortions of magnetic fields due to eddy currents (EC) produced by timeβdependent magnetic field gradients. The EC measuring technique uses a sample with short T~1~,T~2~ and many rf excitation pulses and free inductio
