It is possible to determine one component of magnetic field strength in the electrical steel sheet using thin film magnetoresistive (MR) sensor. Next, using separately measured both components of H, we can merge the results to get the vector of magnetic field strength. The same results may be obtained with the assembly of two sensors. After measurement of the vector values of B and H we can determine electrical steel parameters, like losses and permeability for different directions of excitation. This enables the tensor description of electrical steel parameters.
