Large power plants have big, room-sized generators that produce electricity using magnetic fields from electric magnets. Usually the electric magnets are mounted on a shaft and are connected to the electric power supply. When the electricity is switched on, the electric magnets create powerful magnet...
When the magnets are moved off-axis to each other (moving them to the side and not head on) what does it feel like? Could you describe it like trying to push two tennis balls together? When you flip one around, what changes? What about moving one around the other in a circle? Try...
How do magnets create a magnetic field? How is the magnetic field oriented around a magnet? How does electricity create the magnetic field? How does a magnetic field create electricity? How do scientists detect magnetic fields? How does an electric field produce a magnetic field?
As the copper coils spin within the magnets, electricity is produced. Power lines connected to the generator carry electricity from the power plant to homes and businesses. Westinghouse's Niagara Falls plant was able to transport electricity more than 200 miles (322 kilometers). Not all power ...

Hulton Archive/Getty Images As we've already discussed, a generator converts mechanical energy into electricity. A motor works on the same principles, but in the opposite direction -...
Permanent or hard magnets create their own magnetic field all the time. Temporary or soft magnets produce magnetic fields while in the presence of a magnetic field and for a short while after exiting the field. Electromagnets produce magnetic fields only when electricity travels through their wire ...
Many electromagnets have an advantage over permanent magnets because they can be easily turned on and off, and increasing or decreasing the amount of electricity flowing around the core can control their strength. Electronics Modern technology relies heavily on electromagnets to store information using ...
