Battery: Most phone batteries are unaffected by household magnets. The presence of a very strong magnetic field can cause the battery to work slightly harder to supply the right voltage and thus wearing the battery out faster. However, even a strong horseshoe magnet would not be enough to drain your phone’s battery.

The ferrite beads near the small plug on the USB cables that came with the PLOTS visible/IR camera kit are easy to remove.

USB drives cannot be harmed or altered by magnetic fields. The drives are not built from magnetic materials. So magnets pose no danger to any flash memory including SSDs, SD cards, and external hard drives—even traditional hard drives are immune. In fact, hard drives use powerful magnets to move the head.
