Changing magnetic field creates potential difference

Click For Summary
SUMMARY

The discussion centers on the application of Faraday's law of induction in the context of a loop of wire within an inductor experiencing a changing magnetic field. It establishes that when the current within the inductor changes over time, a potential difference is induced in the loop due to the changing magnetic field. The participant expresses difficulty in reconciling this phenomenon with the Lorentz force and special relativity, highlighting a gap in understanding the relationship between changing currents and induced electric fields.

I can understand Faraday's law when viewed in this situation:

A loop moves into an area of constant magnetic field. I understand this because in terms of the Lorentz force it works and creates the same answer using magnetic flux/faraday's law. Now consider the example of the loop of wire inside an inductor with constant magnetic field throughout the inside. When the current is changed with time this creates a potential difference as well in the loop. I can't understand this in terms of the Lorentz force and thus special relativity. I have searched the forums and online but can't find an adequate solution.

Thanks in advance.

The changing currents create a changing magnetic field which, by Faraday's law of induction, induces an electric Field.
