Adjustable Ferrite Induction Copper Coil Wire Air Core Inductor Magnetic Coil For Audio
The coil generates a magnetic field when it is energized. This is
the magnetic effect of the current. That is, if a straight metal
wire runs an electric current, a circular magnetic field will be
created in the space around the wire. The more current flows
through the wire, the stronger the magnetic field. The magnetic
field forms a circle around the wire.
Principle can be explained by the ampere molecular current
hypothesis: ampere thought in the interior of the atomic and
molecular substances such as particles, there is a ring current -
molecular electric current, make each particle tiny magnets, both
sides of the molecule is equivalent to two pole, but in fact the
molecular electronic instead of turning around the nucleus of the
electron in the probability of the formation of the electron cloud
space.
Define
Magnetic effect of electric current (electric current produces
magnetism) : Oster found that any electric current through the
wire, can create a magnetic field around it, called the magnetic
effect of electric current.
An electric current is applied to a nonmagnetic metal, but a
magnetic field can be created that has the same effect as that
created by a magnet.
The e magnetic field generated around the long straight wire with
current: around the long straight wire with current flow, there
will be a magnetic field generated, the shape of the magnetic
induction line is a closed concentric circle centered on the wire,
and the direction of the magnetic field and the direction of the
current are perpendicular to each other.
