Plan a route, grab some snacks, and fuel up. Engineers and scientists have been sending massive magnets from U.S. Department of Energy (DOE) national labs on cross-country road trips. Magnets are at ...
Key learning points Properties of magnets What are magnetic fields? Magnetic fields lines are invisible but they fill the space around a magnet where the magnetic forces work on magnetic materials, ...
Theorists find new electromagnetic effects that shift the spin-dependent coupling of the nucleon to the weak force and point out the implications for new physics in beta decay. Outside atomic nuclei, ...
The origins of magnetic steel can be traced back to the 18 th century when scientists began experimenting with iron alloys. In 1820, Hans Christian Oersted's accidental discovery of electromagnetism ...
