induktiolankoja

Induktiolankoja, also known as induction coils or simply inductor wire, are essential components in electrical engineering, primarily used to store energy in a magnetic field when electric current flows through them. These coils are typically constructed by winding a conductive wire, most commonly copper, around a core material. The core can be made of various materials, including air, iron, or ferrite, and its composition significantly influences the coil's inductance.

The fundamental principle behind an induktiolanko is electromagnetic induction. When an alternating current flows through the coil, it generates a changing magnetic field. This changing magnetic field, in turn, induces a voltage in the coil itself, opposing the change in current. This property, known as inductance, is measured in Henries (H). The number of turns in the coil, the core material's permeability, and the coil's geometry all affect its inductance value.

Induktiolankoja find widespread applications in various electronic circuits. They are crucial in filtering out unwanted frequencies in radio receivers and transmitters, acting as chokes to block AC signals while allowing DC to pass. They are also integral to transformers, where they enable the efficient transfer of electrical energy between circuits at different voltage levels. Furthermore, they are used in oscillators, resonant circuits, and in inductive charging systems. The design and specifications of an induktiolanko are tailored to the specific requirements of its intended application.
