What about if I have a metal surgical implant?
Nearly all metal implants are made from titanium. Titanium is a paramagnetic material and as such has negligible interaction with magnetic fields. As an example, titanium implants are safe for use in MRI machines which generate strong magnetic fields from large superconducting electromagnets that are many times stronger than Q Magnets. If you are unsure, check with your doctor that your implant is in fact titanium or some other paramagnetic material and you will have no concerns with using Q Magnets over them.
