Magnetic field at the center of the Hydrogen atom
Take 10 minutes to prepare this exercise.
Then, if you lack ideas to begin, look at the given clue and start searching for the solution.
A detailed solution is then proposed to you.
If you have more questions, feel free to ask them on the forum.
An electron travels in a circle of radius around a proton.
Compute the magnetic field created by the electron at the point where the proton is located.
The magnetic field created by the electron at the center of the nucleus is :
Newton's second law applied to the electron gives the velocity of the electron :
We can finally deduce the magnetic field :
Numerically : .
