Method suitable for effective testing of magnetoelastic effect in magnetic materials should fulfill the  following requirements:
* magnetic circuit of the tested sample should be closed. Open magnetic circuit causes demagnetization, which reduces magnetoelastic effect and complicates its analysis.
* distribution of stresses should be uniform. Value and direction of stresses should be known.
* there should be the possibility of making the magnetizing and sensing windings on the sample - necessary to measure magnetic hysteresis loop under mechanical stresses.
Following testing methods were developed:
* tensile stresses applied to the strip of magnetic material in the shape of a ribbon. Disadvantage: open magnetic circuit of the tested sample.
* tensile or compressive stresses applied to the frame-shaped sample. Disadvantage: only bulk materials may be tested. No stresses in the joints of sample columns.
* compressive stresses applied to the ring core in the sideways direction. Disadvantage: non-uniform stresses distribution in the core .
* tensile or compressive stresses applied axially to the ring sample. Disadvantage: stresses are perpendicular to the magnetizing field.
