Types of magnetic materials and their properties with examples

2020/12/13When diamagnetic material is placed within a magnetic field the lines of force tend to go away from the material. When a diamagnetic substance is placed in a watch glass on the pole pieces of a magnet the liquid accumulates on the sides causing a depression at the center which is Get price

The Quartz Page: Physical Properties

2011/09/04If a physical property or value includes information about a direction or is dependent on it, its unit is a vector, for example speed, acceleration, or electrical conductivity. 3 That would be 3 principal axes in a three-dimensional structure, of course, but the figure is only two-dimensional.Get price

Resistivity

Therefore, it is NOT a physical property. Consider current flowing through the unit cube of material shown to the right: resistivity is defined as the voltage measured across a unit cube's length (Volts per metre, or V/m) divided by the current flowing through the unit cube's cross sectional area (Amps per meter squared, or A/m 2 ).Get price

Surface morphology and magnetic property of wrinkled FeGa

2016/03/11We investigated the surface morphology and the magnetic property of wrinkled Fe 81 Ga 19 (FeGa) thin films fabricated in two different processes onto elastic polydimethylsiloxane (PDMS) substrates. The films obtained by directly depositing Ta and FeGa layers on a pre-strained PDMS substrate display a sinusoidally wrinkled surface and a weak magnetic anisotropy.Get price

Rock magnetic study of the Early Paleozoic limestone from

1998/12/01Rock magnetic study was carried out on the samples of non-remagnetized Lower Paleozoic limestone from Henan Province. These studies suggest that the properties of the natural remanent magnetization are usually dependent on the grain size of magnetic carrier, e.g. the grain size of magnetite mineral (multidomain or single domain).
