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.

Scientists have discovered a new reason for turtles to dance for joy: Loggerhead sea turtles seem able to discern and remember magnetic field signatures, which could help them find food.

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 ...
