SUMMARY
Magnetism cannot exist independently of electric charge, as established by classical electromagnetism principles. While a permanent magnet can generate a magnetic field without a current, it still relies on the presence of electric charges within the material. The speculation surrounding magnetic monopoles persists due to their potential to introduce symmetry in Maxwell's equations, despite no experimental evidence confirming their existence. Discussions highlight that magnetism arises from the magnetic moments of electrons, which are inherently linked to their charge.
