Why doesn't a electron moving in a circular orbit create a magnetic field around itself?

Question

moving charges/current creates a magnetic field around the conductor. so why doesn’t an electron? if it does why aren’t all objects magnetic?

Answer 1

If the electron is orbiting a nucleus, it does create a magnetic field around itself. In addition, the electron has an intrinsic magnetic moment due to something we call spin (for lack of any better word to describe a point particle with angular momentum). These magnetic moments interact with each other and the angular momentum of the nucleus to create the fine and hyperfine structures of atomic spectra. So why isn't everything magnetic? The short answer is that everything IS magnetic. It's just that most of the magnetic moments tend to cancel each other out. Within an atom, you usually have a spin up electron for every spin down one. For orbiting electrons (not s=0 states with no angular momentum), the directions of orbit cancel out. So most atoms and molecules have little or no magnetic moment. In materials where the atoms DO have a magnetic moment, they atoms are usually all pointed in different directions, so the magnetic fields pretty much cancel out. So only certain materials under certain conditions will have microscopic magnetic moments that line up in such a way that you can observe a macroscopic magnetic field.

Answer 2

First of all, moving in a circular orbit is a classical description appropriate for electrons in vacuum in a magnetic field, but not atoms. Electrons in nonconductors are bound to atoms in quantized orbitals, although they usually do have angular momentum. Also, remember an atom general has several electrons. It's common for the net electron angular momentum and magnetic dipole moment to be zero due to the electrons being in different orbitals. Even for atoms with a magnetic moment, the material usually has its atoms randomly oriented, leading to no net magnetization. However, all materials do respond to an externally applied magnetic field by become magnetized, if only to a small degrees. This is quantified by it's magnetic susceptibility

Answer 3

May be it makes an manetic field i 90 deg angel with moving direction of the elektron. But you will probably have more than one elelctron moving in the area. Hydrogen always makes molecules H2. May be the pair of electrons disturb the field of each other. And it is not a typical circular moving of the electrons i the orbitals.

Answer 4

It does, and they are to a pair degree. What occurs is that once the electrons party in an atom, they pair up in the style of way as to cut back the magnetic ability - it really is (partly) why the atom's orbitals fill up the way they do. once you've an atom with an straightforward atomic variety, you get unpaired electrons interior the outermost shell. yet those atoms have a tendency both pair up in molecules (H2, N2, and so on.) so as that those electrons pair up, or style crystals and shed the outermost electrons to what's termed the "conduction band" - the electrons stay interior the fabric yet do not stay in orbit around the atoms, making them conductive. All this pairing up makes the magnetic moments cancel out (like putting 2 magnets mutually, north-to-south ploes) leaving a non-magnetic cloth. The electrons themselves also spin on their axis, making them magnetic even at the same time as they are no longer in orbit - back, they pair up in the style of thanks to cut back the magnetic ability. the genuinely physics in the back of it ought to get particularly complicated, yet it really is it in a nutshell.

Answer 5

because electrons make electromagnetic fields, so you cant have a field around a field.

Answer 6

Everything (repeat, EVERYTHING) has a magnetic moment.
