How to Make a (Really) Strong Magnet (opens in new tab)

Ethan Bowers, a Ph.D. student in mechanical engineering at UMBC, is building a massive, one-of-a-kind research magnet. It weighs more than 2,300 pounds and will be capable of generating a magnetic field of 7 teslas (roughly 140,000 times stronger than the Earth’s magnetic field and more than twice as strong as the field in most MRI machines.)
