Electric generators have a plethora of uses—ranging from automotive to aircraft to microgrids. There is currently a strong desire to reduce the size and increase the efficiency of the devices. Researchers at Purdue University have come up with an effective way to reduce the size and increase the efficiency of the moderate- to low-power electric

A magnet housed at the National High Magnetic Field Laboratory in Tallahassee, Florida, has set a record for the strongest continuous DC magnetic field ever recorded with a 45.5-tesla rating. To put this figure in perspective, a small, but strong everyday neodymium magnet scores about 0.2 teslas, while a large electromagnet comes in at around
