The national high magnetic field laboratory holds the world record for creating the strongest magnetic field. for brief periods of time, their largest multi-shot pulsed magnet can produce magnetic fields in excess of 85 t. to see if such a strong magnetic field could pose health risks for nearby workers, calculate the maximum acceleration the field could produce for na ions (of mass 3.8 × 10-26 kg) in blood traveling through the aorta. the speed of blood is highly variable, but 45 cm/s is reasonable in the aorta
