Slightly random Q

I just watched EMG's Geezer installation video and one thing caught my attention. I'm pretty certain that when she taps the pole pieces to verify sound is getting through she's using a screwdriver with a magnetic tip. This doesn't seem like a good idea, but could it actually cause damage to the pickup?

Nah the only thing that could possibly go wrong would be to have your amp turned up to max volume / gain while performing the tap testing (but that would really only potentially harm your speakers & ears, haha)— the screwdriver’s magnetism won’t harm the actual pickups.
The tap test saves time.. who wants to restring their bass before making sure the pickups are actually functioning?
