Traveling through that strong of a magnetic field, that would definitely generate eddy currents. Like dropping a magnet down a brass plate causes it to move very slowly because the magnetic field moving induces current in the plate and the current creates a counter magnetic field. My instinct is that it would just slow it down, But that MRI is spinning magnets. Maybe it just slows down a little and is it noticeable, maybe it spins it while it's slowing it down and amplifies the minute drop due to gravity. Too bad MythBusters are gone. There's not many people out there funded well enough to test shooting bullets through an MRI machine.
Wait if the bullet is generating Eddy current can we get electric bullets by shooting bullets through an MRI like shooting an arrow through fire to get a flaming arrow.
The bullet would not be generating an eddy current.
The eddy currents are induced in the bullet by the magnetic fields as it passes through.
It’s like a generator’s coil that doesn’t have anything attached to it. Because there’s nowhere for it to go, the eddy currents just dissipate when it leaves the magnetic field.
Bullet time, baby.
