High Quality Flat Copper Wire Coil Core, RFID Copper Coil/RFID Air Coil Antenna Coil
Air Core Induction Coil
Inductance coil was conducted by using the principle of electromagnetic induction device.When a current flows through a wire, will produce certain electromagnetic field around that wire, and the electromagnetic field of the wire itself will be in within the scope of the electromagnetic field in the conductor induction effect.To generate electromagnetic wire itself, is called a "feeling", i.e., the change of wire itself the changes in the current magnetic field, the magnetic field and further influenced the current in the conductor;On the role of electromagnetic field in the range of other wires produce, called "mutual inductance.
Inductance is a wire by
alternating current, in the interior of the wire and the
surrounding to produce alternating magnetic flux, conductor
magnetic flux and the flux of the ratio of the current production.
When the dc inductance of
the current through its only present fixed around magnetic field
lines, does not change with time;But when by alternating current in the coil, the surrounding
magnetic field lines will appear over time changes.According to the ferrari brother's law of electromagnetic
induction, magnetic electricity to analyze, change the lines of
magnetic force on both ends of the coil can produce induction
electric potential, the induction electric potential is equivalent
to a "new power".When form a closed loop, the induction electric potential to
produce induced current.Produced by lenz's law know induced current amount of magnetic
field lines to keep the original of the change of the magnetic
field lines.Changes due to the original lines derived from plus alternating
power supply, therefore, from the objective effect, inductor have
block communication, change characteristics of current in the
circuit.Inductance coil have similar characteristics and mechanics of
inertia, called "self induction" on electricity, usually in the
open or connect knife switch, knife switch can produce sparks, this
is self inductance phenomenon produces high induction electric
potential
