Custom Small Double Layer Copper Self-Bonded Induction Air Coil
Inductive coil The self-induced electromotive force in the coil
always counteracts the current change in the coil. Inductance coil
has a blocking effect on ac current, the size of the blocking
effect is called inductive reactance XL, the unit is ohm. Its
relation with inductance l and ac frequency f is XL =2πfl.
Inductors can be divided into high frequency choke coil and low
frequency choke coil.
Folding tuning and frequency selection
An LC tunable circuit can be formed by an inductor coil in parallel
with a capacitor. That is, the natural oscillation frequency of the
circuit f0 is equal to the frequency f of the non-AC signal, so the
inductive and capacitive reactance of the circuit are equal, so the
electromagnetic energy oscillates back and forth in the inductor
and capacitor, which is the resonance phenomenon of the LC circuit.
When resonant, the inductive reactance and capacitive reactance of
the circuit are equivalent to reverse, the total circuit current
inductive reactance is the minimum, the current is the maximum
(refers to the AC signal f=" F0 "), lc resonant circuit has the
role of selecting frequency, can select the AC signal of a certain
frequency F.
