10 Questions
Who discovered magnetostriction and in what year?
Joule discovered magnetostriction in 1842.
What is the symbol used to represent the magnetically induced strain?
The symbol used to represent the magnetically induced strain is l.
What is the value called when the longitudinal magnetostriction is measured at magnetic saturation?
The value measured at magnetic saturation is called the saturation magnetostriction ls.
What are some other magnetostrictive effects aside from longitudinal magnetostriction?
Other magnetostrictive effects include magnetically induced torsion or bending of a rod, which are considered special cases of the longitudinal effect.
In strongly magnetic substances, what is the typical order of magnitude for the saturation magnetostriction ls?
The saturation magnetostriction ls is typically of the order of 10^-2 to 10^-5.
What is magnetostriction and when was it discovered?
Magnetostriction is the change in dimensions of a substance when exposed to a magnetic field. It was discovered in 1842 by Joule.
What is the symbol used to distinguish the magnetically induced strain from the strain caused by an applied stress?
The magnetically induced strain is given the special symbol l.
What is the value called when the longitudinal magnetostriction is measured at magnetic saturation?
The value of the longitudinal magnetostriction measured at magnetic saturation is called the saturation magnetostriction ls.
What is the typical order of magnitude for the saturation magnetostriction ls in strongly magnetic substances?
The typical order of magnitude for the saturation magnetostriction ls in strongly magnetic substances is typically of the order of 10^-25.
In terms of stress, how much stress would be produced by a strain of 10^-25, considering Young’s modulus is 30*10^6 lb/in2?
A strain of 10^-25 would be produced by an applied stress of only 300 lb/in2 or 2 MPa if Young’s modulus is 30*10^6 lb/in2.
