Study and analysis on the Magneto Elasticity of engineering material

Subhankar Moulick

Abstract


In the present paper, the phenomenon of magneto-elasticity was observed with fatigue and tensile testing of cast aluminum specimens. The residual amount of magnetism retained by the material was picked up using a coil connected to an amplifier. The residual magnetic lines of force generate an e.m.f. in the pickup coil during the separation of the two pieces at failure. This e.m.f. was recorded as a peak in the voltage. The fluctuating magnetic lines of forces through the coil also gave rise to a periodic pattern which was witnessed in the oscilloscope.
