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.
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 ...
where electricity comes from, or explaining how magnets work or experiments you did with magnets. Cloverbuds may also make an electromagnet or make a battery from a potato. Cloverbud projects are for ...
"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 ...
