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

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.

A trio of US researchers claim to have successfully tested predictions that it's possible to harvest clean energy from the ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

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.

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 ...

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 ...
