The discussion centers on the magnetic fields produced by moving protons and electrons, particularly in circular motion within a magnetic field. It explores the application of the right-hand rule and Biot-Savart's law in this context.
Participants express differing views on the application of the right-hand rule to protons and electrons, indicating a lack of consensus on the implications of charge sign in determining magnetic field direction.
Some assumptions regarding the magnitude of the magnetic fields produced by protons compared to surrounding fields remain unaddressed. The discussion does not resolve the implications of the differences in charge sign on the magnetic field direction.
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.General Scientist said:If an electron is moving in a circle in a magnetic field, it produces a magnetic field in accordance to the right hand rule. If a proton is moving in a circle in a magnetic field, would it produce a magnetic field in accordance to the left hand equivalent to the right hand rule.
So the positive charge of a proton would mean the magnetic field is just ##\vec{v} \times \vec{r}##?Charles Link said: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} ##.General Scientist said:So the positive charge of a proton would mean the magnetic field is just ##\vec{v} \times \vec{r}##?
Ok. Thank you.Charles Link said:See the part I added to post 3=the formula for ## \vec{B} ##.
