I know it’s kind of a stupid question, but I have been thinking this for a while. Do magnets affect the electricity itself that flows inside a wire? For example, say I am charging my phone and it’s connected to a wall socket. If I placed a magnet in the middle of my charger wire (like literally on top of the wire) would the magnet stop the electricity from flowing since it’s getting attracted to the magnet? Would it have any effect at all on the flow of electrons inside the wire?

For the purposes of your concern, not really. A *changing* magnetic field will create an electric field, and a *changing* electric field creates a magnetic field. But static fields don’t do much.
They don’t do zero. A static magnetic field can affect an electric current via the [Hall Effect](https://en.wikipedia.org/wiki/Hall_effect). But that won’t really have much impact unless the magnetic field is quite strong.
So the more precise answer to your question is “Yes, it does have an effect. But not much of one in the situation you describe.”
