So when an object spins (like the electron), it is said to have a magnetic moment. Now, I do not understand what they mean when they say that it has a magnetic moment.
When I did research, I saw this picture from which I assumed that the magnetic moment is nothing but the magnetic field of the electron. Is my this hypothesis wrong?
I also read that spin up and spin down refer to positive and negative magnetic moments. If this is the case, then clearly a magnetic moment is not a magnetic field.
So I am getting very confused as to what a magnetic moment for an electron means.
