Good question. I'd love to know as well. Bohm (QT book) wrote that the magnetic field is roughly 100X smaller than the electric field, but I did not read if that was experimentally measured or estimated from a calculation.Norman said:How do you separate these two cross sections in an experiment?
Sorry, but that's the best way I know how to put it.Norman said:A scattering cross section needs a reaction, so what would your reacton be or in other words, what is being scattered and by what? I am not sure I understand what you are asking and if I do, then your question may be ill-posed.
Actually, I'm interested in the effective volume and the radial density of both. Does that help?Norman said:Are you trying to get a feel for the relative strength between them?

The size of the magnetic field for an electron is much smaller than the size of the electric field. The magnetic field is typically measured in units of Tesla, while the electric field is measured in units of volts per meter. This means that the electric field is significantly larger in magnitude than the magnetic field.
This is due to the fact that the electric field is generated by a point charge, which is the electron, while the magnetic field is generated by a moving charge. Since the electron is much smaller than the distance it travels, the magnetic field is greatly reduced.
The size of the magnetic field follows the inverse square law, meaning that it decreases as the distance from the electron increases. This is because the magnetic field is spread out over a larger area as it travels away from the electron.
No, the size of the magnetic field can vary depending on the direction of measurement. This is due to the fact that the magnetic field is a vector quantity and has both magnitude and direction. The size of the magnetic field will be largest in the direction perpendicular to the motion of the electron and will be zero in the direction of motion.
Yes, the size of the electric and magnetic fields can be measured separately using different experimental techniques. The electric field can be measured using a device called an electric field probe, while the magnetic field can be measured using a device called a magnetometer. These measurements can then be compared to determine the relative sizes of the two fields.
