SUMMARY

Distance does affect the electromagnetic field (EMF) according to Faraday's Law, which states that electromotive force (emf) is equal to the rate of change of magnetic flux through a circuit. While the emf generated is dependent on the change in flux, the strength of the magnetic flux diminishes with distance from the source, such as an inductor. Therefore, the emf experienced by a coil is contingent upon its proximity to the source of the changing magnetic field, and not all electronics induce voltages uniformly across distances.

This is just a general question, no calculations or homework-like wording involved! It's just a little something that has been bugging me.

Faraday's law states emf = change in flux with respect to time. Let's say I'm generating this change in flux with an inductor somewhere in space. (I want all of the flux in a fixed "area" for this).

Now, since Faraday's law only states the emf is dependent upon change in flux, doesn't this mean that no matter how far I am from the inductor, I get the same emf? If so, shouldn't we be experiencing emf from electronics all the time, interfering with and inducing voltages everywhere?

Thanks for taking a look at this! :)

Strength of flux depends upon the distance of the source from the coil. Coil must be exposed to the change of flux to produce emf.
