The silicon steel sheet is a soft magnetic material, but no magnetic charging transformer core was a magnet for a long time, why suck?
Ferromagnetic materials have the commonness of being adsorbed by magnetsThe soft magnetic itself has no obvious magnetic characteristicsA magnet (magnet) has magnetic properties and exhibits magnetic domain coherence, so it has magnetic properties that can adsorb iron, nickel, cobalt... Ability
The silicon steel sheet is soft magnetic materials, no magnetism is absolutely correct, soft magnetic material is not magnetized and remanent materials, and not by a magnet sucking material, under the action of current, the soft magnetic material to generate magnetic force, but it will not remove the current magnetic tape, of course, also can use magnets suck it, transformer is the use of its characteristics as the core, compared with hard magnetic materials, magnetic material will be magnetized with remanence itself becomes a magnet, this is the biggest difference.
The difference between soft and hard magnetic is soft magnetic field will recede its magnetism and magnetic in the corresponding receded, the magnetic field receded still exist. Is mainly soft magnetic remanence is relatively small, and the relatively large magnetic remanence.
