Difference of Magnetic Memory Testing Signal on Different Direction

In order to study how the inspection direction affects magnetic memory signal, experiment has been carried out to detect normal component Hp(y) of magnetic field out of tensile samples along different directions. Results show that the normal component Hp(y) was different when detecting along different direction, and the position of zero point of the normal component Hp(y) was shifted away, but the value of magnetic parameter and the gradient of the normal component Hp(y) showed small deviation.
