Magnetostrictive waveguide wire for level gauge
An important characteristic of a wire made of a magnetostrictive material is the Wiedemann effect.
When an axial magnetic field is applied to a magnetostrictive wire, and a current is passed through the wire, a twisting occurs at the location of the axial magnetic field.
The twisting is caused by interaction of the axial magnetic field, usually from a permanent magnet, with the magnetic field along the magnetostrictive wire, which is present due to the current in the wire
The current is applied as a short-duration pulse, -1 or 2 us; the minimum current density is along the center of the wire and the maximum at the wire surface. This is due to the skin effect.
The magnetic field intensity is also greatest at the wire surface
This aids in developing the waveguide twist
Since the current is applied as a pulse, the mechanical twisting travels in the wire as an ultrasonic wave
Magnetostrictive wire is therefore called the waveguide
