ferromagnetic material उदाहरण वाक्य

Ferromagnetic materials owe their properties to an enormous number of embedded tiny magnets, called domains.
A familiar example of SSB is in ferromagnetic materials.
Think about a permanent magnet and a chunk of ferromagnetic material ( like iron ).
Computing the magnetic field and force exerted by ferromagnetic materials is difficult for two reasons.
But in a ferromagnetic material, all the atomic moments are aligned even without an external field.

A modern HDD records data by magnetizing a thin film of ferromagnetic material on a disk.
It turned out, for example, that small clusters of a ferromagnetic material are super-paramagnetic rather than ferromagnetic.
Even an iron ( " soft " ferromagnetic material ) nail can retain a bit of the magnetization.
The magnetic moments of atoms in a ferromagnetic material cause them to behave something like tiny permanent magnets.
This can result in ferromagnetic materials having no spontaneous magnetism as domains could potentially balance each other out.
