magnetization (the same as rolling direction and

the movement direction), the method is relative by

easy; the sheet is enwrapped by magnetizing and

secondary sensing coils supported by the yoke, which

improves the magnetic eld distribution (Figure 5.18a).

The H-coil was used as the magnetic eld strength

sensor.

More difcult is testing of the samples magnetized

perpendicular to the rolling direction; a proposal for

this case is presented in Figure 5.18b. The secondary

coils are inclined by ±45° and in this way two compo-

nents of the polarization are measured (or
