Scientists now show that, contrary to previous belief, superconductivity can induce magnetism, which has raised a new quantum conundrum. When an electrical current passes through a wire it emanates heat – a principle that's found in toasters and incandescent light bulbs.

Are superconductors magnetic?

One of the fundamental properties of a superconductor is that it hates magnetic fields. If a scientist applies a magnetic field, the superconductor creates its own equal and opposite magnetic field.

Can any metal be a superconductor?

But at very low temperature, some metals acquire zero electrical resistance and zero magnetic induction, the property known as superconductivity. Some of the important superconducting elements are- Aluminium, Zinc, Cadmium, Mercury, and Lead.
