Summary[edit]
| Description |
English: Most students are taught that protons have charge and that they also have angular momentum -- a fancy way of saying that they are spinning. Most students are also taught that protons have a magnetic dipole. The two concepts are inherently connected, but this is usually not addressed in basic chemistry classes.
The first misconception that needs to be addressed is that protons are points. In fact, they encompass a certain volume. Secondly, their charge is not concentrated all at their center but is distributed, albeit unevenly, throughout their volume. Since a proton has charge in its volume, and it is spinning, it is effectively a charge spinning in a circle. This is no different from the case of a coil or the earth spinning, and this is the reason protons create a magnetic dipole, which is just another word for the magnetic field it creates. Compare this proton to the coil in the previous slide to see the similarity. |
