Bimetallic cylinder in a pulsed magnetic field

The magnetic field diffusion into a bimetallic cylinder comprising a central rod and the outer shell made of different conducting materials is analytically described. In the case of an external field pulse representing a half-wave B _e = B _msin(πt/T), the cylinder exhibits delamination, which is caused by the shell expansion under the action of a residual magnetic field present in its internal cavity. The pressure of this residual field nonmonotonically depends on the conductivity of the rod.
