SUMMARY

Electrons do not attract each other like permanent magnets due to the overwhelming repulsion from their electric charge. In most circumstances, the magnetic attraction is negligible compared to this repulsion. Specific conditions may allow for magnetic interactions, but the magnetic moment of the electron is too small to result in a net attraction. Instead, the alignment of electron spins can modulate the strength of their repulsion, affecting their energy levels.

PREREQUISITES
  • Understanding of electric charge and its effects
  • Basic knowledge of magnetic fields and magnetic moments
  • Familiarity with electron spin and quantum mechanics
  • Concept of energy levels in quantum systems
NEXT STEPS
  • Research the concept of electric charge and its implications in particle physics
  • Explore the principles of magnetic moments in quantum mechanics
  • Study the effects of electron spin on energy levels in atoms
  • Investigate specific conditions that may lead to magnetic interactions between electrons
USEFUL FOR

Physicists, students of quantum mechanics, and anyone interested in the fundamental interactions of subatomic particles.

Do electrons attract to each other like permanent magnets?

Not really. The repulsion from their electric charge overwhelms any magnetic attraction in most circumstances. There may be some very specific circumstances where this comes into play, but for the most part the magnetic field from their own spin has little effect on them.
 
As Drakkith mentioned, the magnetic moment of the electron is small enough that it never leads to a net attraction. However, it can definitely modulate the strength of the repulsion so that pairs of electrons aligned in different ways will have different energies.
