Permanent magnets are the result of ferromagnetism. The prefix "ferro" refers to iron because permanent magnetism was first observed in a form of natural iron ore called magnetite, Fe3O4. Pieces of magnetite can be found scattered on or near the surface of the Earth, and occasionally, one ...
Electromagnetic radiation is a form of energy that includes radio waves, microwaves, X-rays and gamma rays, as well as visible light.
Is magnetism a form of electricity? How strong is Earth's magnetic field? Does Earth have a magnetic field? Why is no work done by the magnetic force? Are electromagnetic waves affected by magnetic fields? Is magnetism chemistry or physics? Discuss. Can the Earth lose its magnetic field? Wh...
The main difference between them is the presence of magnetism. Electricity can be present in a static charge, while we can feel the presence of magnetism only when there are moving charges as a result of electricity. All in all, electricity can exist without magnetism, however, magnetism canno...
Sun: surface magnetismIn a previous work, we reported on the discovery of supersonic magnetic upflows on granular cells in data from the SUNRISE/IMaX instrument. In the present work, we investigate the physical origin of these events employing data from the same instrument but with higher ...

The peak in the spin susceptibility is consistent with a possible ferromagnetic state at T = 0. The onset of such magnetism would convert the quantum spin Hall to a quantum anomalous Hall effect. While such a symmetry-broken phase typically is accompanied by a gap, we find that the ...
