A wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new ...

Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) have developed an innovative method ...

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.

Physical Review Research, 2025) "This small demonstration system generates a continuous DC voltage and current of the (low ..

Tiny magnetic "flowers" engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These ...

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 ...

Instead of applying the responses of materials to an external electric field, it links the static (DC) and dynamic (AC) responses of a material following its interaction with magnetic fields.

increasing the rate of rotation increasing the strength of the magnetic field increasing the number of turns on the coil The diagram shows four different positions of the coil in a dynamo ...
