Are magnetic levitation feet safe with hard drives?

Are streamers safe on magnetic feet?
This video shows an experiment, putting a hard drive directly on three Ukishima 15 feet, to see if the drive is affected by the magnetic field.
I found no adverse effects on the performance of the drive, I also tried it at different angles to replicate different mounting arrangements in streamers with no issues.
