The coupling of energy from one circuit to another that results from the magnetic field generated by the source conductor.
The transfer of energy from one circuit to another by virtue of the mutual inductance between the circuits. Coupling of two coils by means of magnetic lines of force. In transformers, coupling applied through magnetic lines of force between the primary and secondary windings.
In a typical crossover, coils are not placed close to each other because of the inductive interaction between coils.
When signals or noises are coupled magnetically into a wire or cable. This is the principle that allows transformers to function, a good thing, and that can let unwanted signals creep into parts of an audio system, a bad thing.
Magnetic linkage between physically unconnected signal paths or devices.
A method of applying the signal from the transmitter onto the target line without a direct connection. The two types of inductive coupling are direct and indirect. ~ Direct inductive coupling - A form of coupling, wherein the signal from the transmitter is applied to the target line by means of an inductive clamp. The jaws of the inductive clamp are spring-loaded such that they may be snapped around the line. This mode is used when direct connection is not possible. ~ Indirect inductive coupling - A method of coupling, wherein the signal from the transmitter is applied to the target line by means of an internal antenna in the transmitter. The transmitter is placed near the line, and the signal is induced in the line. This is the least effective way to apply a signal, and it may result in bleed-over of the signal to other conductors nearby.
A system that uses the inducing of a current in a coil as a means of transferring data or power. This is sometimes used as a method of transmitting data between tags and readers.
A method of transmitting data between tags and readers in which the antenna from the reader picks up changes in the tag's antenna.
Systems, which use the inducing of a current into a coil as a means of transferring data or power, are said to use inductive coupling.
Crosstalk resulting from the action of the electromagnetic field of one conductor on the other.
The transfer of energy from one circuit to another by virtue of the mutual inductance between the circuits. Note 1: Inductive coupling may be deliberate and desired (as in an antenna coupler) or may be undesired (as in power line inductive coupling into telephone lines). Note 2: Capacitive coupling favors transfer of higher frequency components, whereas inductive coupling favors transfer of lower frequency components.
Systems that use the inducing of a current in a coil as a means of transferring data or power.
A RFID reader antenna and a tag antenna each have a coil, which together form a magnetic field. The RFID tag draws electrical energy from this field, which powers its microchip. The microchip then changes the electrical characteristics of the tag antenna. These changes are sensed up by the reader antenna and converted into a serial number for the RFID tag.
Method for transmission of data and power using coils to transmit and receive electromagnetic fields. Inductive coupling is commonly used for RFID systems and contactless smart cards.
Noise that is transmitted through a magnetic field to surrounding wires.
In electronics, inductive coupling refers to the transfer of energy from one circuit component to another through a shared magnetic field. A change in current flow through one device induces current flow in the other device. The two devices may be physically contained in a single unit, as in the primary and secondary sides of a transformer, or may be separated as in the antennae on a transmitter and a receiver.
