You are correct as magnetic fields are created by moving charges, and the example would satisfy the criteria. Although, I assume it would be tiny compared to the surrounding magnetic field. The right hand rule would work for a proton.

So the positive charge of a proton would mean the magnetic field is just ##\vec{v} \times \vec{r}##?The magnetic field for both is described by Biot-Savart's law. With a negative charge on the electron, its magnetic field is opposite the direction given by ## \vec{v} \times \vec{r} ##.

See the part I added to post 3=the formula for ## \vec{B} ##.So the positive charge of a proton would mean the magnetic field is just ##\vec{v} \times \vec{r}##?

Ok. Thank you.See the part I added to post 3=the formula for ## \vec{B} ##.
