WHAT YOU NEED: stationery to make a small ... The moving magnetic field from the spinning magnets induces a current in the coil of wire. You have made your own electricity generator!

A rare-earth barium copper oxide (REBCO) is now being used by an Oxfordshire-based company for its superconducting properties ...

Different energy sources used to make electricity ... the middle has a circle of magnets around its edge. When this spins, electricity flows through the coils of copper wire that surround it.

"This is superconducting magnetic ... zero-carbon electricity from abundant, naturally occurring elements. But has, since the 1950s, remained out of reach. The challenge is how to create, then ...

the magnets create a rapidly flipping magnetic field. To test this setup, [Tim] used a scrap of copper pipe with a bit of water inside. Holding it over the magnets as they whiz by rapidly heats ...
