Materials are known to interact with electromagnetic fields in different ways, which reflect their structures and underlying ...

If the current is dc, the ends of the iron will become a ... They lose most or all of their magnetism when they are removed from the magnetic field.

DC SQUID: A DC SQUID consists of two Josephson junctions connected in parallel in a superconducting loop. When an external magnetic field is applied, it induces a current in the loop, which is ...
