Can I re-magnetize my sensory magnets?

Magnets.
I've had sensory magnets installed since November 2016. I bought the magnets and had them installed by Steve Haworth. As of July 2020, you can now buy his magnets for installation elsewhere. https://store.stevehaworth.com/collections/magnets
Since then I have been able to notice some key differences, and in 2018 started to notice sensory loss. I have a very large magnet at home, which before was impossible to touch, and now I can rest my right magnet on it.
While this is a brief post, I am posting my intention to remagnetise the magnets. I've attempted and gave this up previously, because the process is uncomfortable. However, I must do it in order to keep the magnetic sense.
I'm using different sized magnets to move the sensory magnets in my finger to strengthen them and break down some of the scar tissue in my finger to let them move freely.
Reps. This is the big magnet I'm using. I found there's two different things I'm trying 1. Running my finger acro…

Why I really want a walkthrough metal detector

So if you saw my GrrCon 2019 talk, you know that I've been looking for a walkthrough metal detector. I will be working a summer position that will pay me enough to purchase a walkthrough metal detector. Currently, I have a Twitter poll asking if this was a good idea.
What are you going to do with the metal detector? I used to have access to a walkthrough metal detector (WTMD) through my research lab. My friend Katie and I nicknamed the metal detector Mr. Den City. I had access to the WTMD but of course, within limits. We made certain agreements with those we borrowed the detector from, and it technically wasn't ours, but our leader's. Still, I have some POCs which demonstrated interference and modification of WTMD results, and I want to recreate, improve, and document these findings.
Is there a specific walkthrough metal detector that you need? I'm looking for a Garrett 6500i or another model in that family. I'm also looking for the networking modules for the device.…

Can you hack a security checkpoint metal detector? Yeah, we already did.

To get straight to the point - walkthrough metal detectors are a security technology to attempt to detect and thus remove weapons and dangerous items from individuals to make a safe space. What if they were much more fallible than expected?
I'm not here to fear-monger either - these problems are preventable with proper use and changed in guidelines. Like many security controls, their exploitation is commonly due to those who implement and monitor them. However, in order to create these changes, more proof-of-concepts and solutions need to be tested. We already have a few to start.
The walkthrough metal detector (WTMD) research was not my original idea. It started out of research projects from PHSI and another Garrett 6500i was donated to our lab. This machine was not ours and we did not have permission to modify or conduct digital attacks on the detector. We were supposed to use physical modifications to hide or modify the results of the screening.
