If you have a one solenoid inside another (with the same number of coils of wire) the current is going through the inner one. How does the induced EMF in the outer one depend on the frequency of AC in the inner one

AC frequency refers to the rate at which the direction of an alternating current (AC) changes. It is measured in hertz (Hz) and is typically used to describe the frequency of the power supply in a circuit.
Induced EMF (electromotive force) is the voltage that is induced in a conductor when it is exposed to a changing magnetic field. This can occur when a conductor moves through a magnetic field or when a magnetic field changes in strength.
The higher the AC frequency, the greater the induced EMF will be. This is because a higher frequency means that the direction of the current changes more rapidly, resulting in a stronger induced EMF in the conductor.
The relationship between AC frequency and the strength of induced EMF is directly proportional. This means that as the AC frequency increases, the strength of the induced EMF also increases. Similarly, as the AC frequency decreases, the strength of the induced EMF decreases.
AC frequency is an important consideration in power generation and transmission. In generators, the AC frequency determines the speed at which the rotor must spin to produce a specific frequency. In transformers, the AC frequency affects the efficiency of energy transfer and can impact the design and size of the transformer. It is also used in various electronic devices, such as induction cooktops and wireless charging systems.
