‘Little big coil’ breaks record for world’s strongest magnet

Researchers at the US MagLab have built the strongest magnet on Earth, which they nicknamed little big coil (LBC). With a magnetic flux density of 45.5 Tesla, it is 9000 times more powerful than a typical fridge magnet and almost half as strong as a chemical bond-distorting magnetic white dwarf star. Unlike its giant 45T predecessor – which held the record for almost two decades – the new setup is smaller and uses much less power.
