Rod Core Ferrite Coil

Rod Core Ferrite Coil is a device that operates on the principles of electromagnetic induction. Magnetic field around the coil appears because of the AC current in the copper winding. Ferrite rod core provides high magnetic permeability and thus increases the concentration of the magnetic flux and the inductance of the coil.

During receiving applications, the ferrite rod is exposed to time-varying magnetic field produced by external electromagnetic waves. Time-varying magnetic flux induces electrical signal in the winding and it is further processed by electronic circuits.

Rod Core Ferrite Coils will enhance the efficiency of magnetic coupling and the coil will be able to receive weaker signals compared to air-core designs. Performance depends on properties of the ferrite material, size of the core, winding turns, frequency and matching with the circuit; the correct design will ensure high sensitivity, low energy losses and stable signal transmission.
