Why are people who get the Jab becoming magnetic?

When videos showing that magnets are attracted to the place where people were injected with the Frankenvax first started appearing, I was very skeptical. However, now that multiple people are experiencing this same phenomena I'm starting to think that there's something to this.

Why would an injection site become magnetic?
Are these people chipped like they all seem to think?
What's going on here?

Many questions but very few answers. Whatever is causing this to happen, it certainly warrants further investigation.
