Abstract :
A simple technique of measuring the dynamic magnetostriction in silicon-iron using displacement transducers is discussed. The importance of stress and harmonics of magnetostriction is shown by considering the effects of improving the stress sensitivity of steel and reducing core vibration by a suitable bonding technique which can also reduce transformer noise.
