Airport security: almost never a problem. MRI: always take them off. The magnets in a magnetic earring are tiny, but an MRI scanner is not a metal detector and treats any ferromagnetic object as a hazard.

Airport security

Checkpoint What happens Advice
Walk-through metal detector A 1 g steel stud with a 5 mm magnet is below the alarm threshold at most airports Leave them on
Millimeter-wave body scanner May show as an anomaly on the ear like any earring Expect a quick pat of the ear if flagged
Hand wand Will beep, like any earring Show the earring; it takes seconds
Laptop and phone in the tray The back magnet can stick to the tray edge Keep spares in a pouch, not loose

MRI

Remove magnetic earrings before an MRI, along with every other piece of jewelry. The scanner magnet is thousands of times stronger than the earring magnet; the earring can be pulled off the ear, heat up, or distort the image. Radiology staff will ask; take them off before you go in.

Pacemakers and implants

The earring magnet is far too weak to affect a pacemaker at chest distance, but manufacturers of implants publish their own guidance and it always wins over ours. Keep magnets away from the implant site and ask your doctor if in doubt.
