Homework Statement
Not sure if I'm correct or wrong..because usually M12 = M21
The Attempt at a Solution
Here coil 1 and coil 2 are coaxial, with coil 2 being shorter and having smaller area.
Mutual inductance is a phenomenon that occurs when two coils are placed near each other, causing a change in the magnetic field of one coil to induce a voltage in the other coil.
The mutual inductance of coaxial coils is based on the principle of electromagnetic induction. When an alternating current flows through one coil, it creates a changing magnetic field. This changing magnetic field then induces an alternating current in the other coil, causing a voltage to be produced.
The mutual inductance of coaxial coils is affected by the number of turns in each coil, the distance between the coils, and the permeability of the material between the coils. The shape and orientation of the coils also play a role in determining the mutual inductance.
The mutual inductance of coaxial coils can be calculated using the equation M = μ0 * N1 * N2 * A / l, where μ0 is the permeability of free space, N1 and N2 are the number of turns in each coil, A is the area of the coils, and l is the distance between the coils.
Mutual inductance of coaxial coils has various applications in electrical engineering, such as in transformers, motors, and generators. It is also used in wireless power transfer systems, where the mutual inductance between two coils is used to transfer energy without the need for physical contact.
