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.
