So, what is magnetic coupling? The other name of Magnetic Induction Couplings is inductive coupling. This happens when energy is coupled from one circuit to the other circuit. This in turn takes place through a magnetic field. Another thing to note is that this mostly happens when the impedance of the source circuit is low because currents are sources of magnetic fields.
In other words, two conductors are said to be magnetically coupled when the configuration is done in a way that change in current through one wire leads to inducement of voltage across the other wire. These all are done through electromagnetic induction. When the current changes through the first wire it leads to the creation of changing magnetic field around it. Further, we note that Magnetic Induction Couplings is facilitated through Ampere’s Circuital Law in action. Now, again, the changing magnetic field will induce an electromagnetic force in the second wire. This is facilitated with Faraday’s Law of Induction in action.
If one has to measure inductive coupling between the two conductors then the correct way to do so is by measuring the mutual inductance. Let us check out some more information related to Magnetic Induction Couplings.
If you are looking to increase the coupling between two wires, do it by winding them into coils and having them placed close to each other on a common axis. This will enable the passing of the magnetic field of one coil through another coil. The other way to increase the coupling is by increasing the magnetic core of ferromagnetic materials like iron. This happens because due to this process the magnetic flux increases.
