Experts to introduce the composition and properties of magnets to you
First of all, magnetic component is iron, cobalt, nickel and other atoms arranged by internal structure is special form, the original magnetic steel itself has a magnetic moment.
In general, the arrangement of these mineral molecules is relatively more chaos.
And their magnetic magnetic to interact with each other and show, but in the external force (
Such as magnetic field)
Guided by the molecular orientation will tend to magnet is consistent, its magnetism will be displayed significant differences.
Soft magnet permanent magnets and magnet, permanent magnet is coupled with a strong magnet, make the spin of magnetic materials and electronic angular momentum into fixed direction, soft magnetic is combined with current (
Is also a kind of combined with magnetic method)
Such as current remove soft magnetic iron will slowly lost.
The earliest discovered and use the magnet should be Chinese & other
The compass & throughout;
, the compass is one of the four great inventions of China.
Basic properties of magnets to 1.
The nature of the magnet: magnet magnetic, can attract iron objects.
Magnet has a magnetic pole, each magnet manufacturer production magnets are two magnetic N pole and S pole, is exist in pairs.
A temporary magnet and permanent magnets: when a ferromagnetic material is magnetized, easy to lose the nature of the magnetic, is called a temporary magnet (
For example, iron)
When a ferromagnetic material is magnetized, not easy to lose the nature of the magnetic, is called a permanent magnet (
For example: steel)
When two magnets near each other, will the same magnetic poles repel each other away, don't stick the same magnetic pole will be attracted to each other.
So say: with poles repel, heteropolar attraction it is for this reason.
