Chances are I'll be able to discuss it with the technician or get it removed prior.

which is about 1 in 9 people. If those scans were evenly distributed everyone would get several in a lifetime although there is probably a Pareto thing going on to the effect that "20% of people get 80% of the scans".
It's pretty routine for common soft tissue injuries. My son got a minor injury at work and had a Workman's Comp claim and got his knee scanned (puts a bound on liability I guess); I got my knee scanned because I'd had patello-femoral pain for a while and wanted to try steroid injections (didn't stick with it, my wife has given steroid injections to numerous horses, she tells me it helps in the short term but not the long term) Like my scan his scan came back with "degenerative changes consistent with your age".
It may be a waste in most cases

I think having it externally would be an inconvenience, and if it wasn't done constantly, I don't think the brain would learn to interpret it in quite the same way. It'd also likely get in your way during daily tasks. Ideally, you want to put it in a location with high sensation (this is why many people choose their fingertips), so any advantageous location would probably be a hindrance.
You could always wear a magnetic ring for lifting, though. I actually purchased my father a magnet-filled wristband for holding screws, bolts, etc, once I realised the utility of such a thing via my implant.
Improbable but i just don’t think the fun is worth it lol
I also have an RFID/NFC implant and currently use it to get into my apartment. Have also used it for work and school cards in the past, it's easy to write new cards to it if the chip in the card is one that can be easily copied (most can).
Maybe the magnet was detected but as I have my hands out and fingers spread a visual check would dismiss any threat. The same could be said for non-magnetic steel implants I have - one in each hand.
Implanting seems to come with several drawbacks: infection risk, difficulty of removal if undergoing an MRI, and difficulty passing through security checkpoints.
The advantage is... Saving 5 seconds when compared to just wearing a glove with magnets in it? A glove would also likely provide far far better sensing (more and stronger magnets better placed).
Also, some people just seem to have a fetish for poking metal bits into themselves.
Maybe it's good for first dates or something, "wanna feel the lumps in my hand" is a bit more intimate than "wanna feel my glove"
The second use case of dragging paper clips is even more confusing. I get the novelty I guess, but that's really worth the risk of the magnet hurting you in some way?
They mentioned it being strong enough to pick up scissors or a knife, that seems like a pretty easy way to accidentally slice open the side of your hand. The risk of coming across another strong magnet that snaps onto the meet of your hand also seems like it could be really annoying and painful, like pinching the side of your hand in a drawer.
"I bet I can lift that paperclip 6 inches off the table with one finger"
Mine is not strong enough to lift much more than a paperclip. However, I have many magnetic fidget toys and when one of those attracts to the finger magnet it does strongly which impedes blood flow to the skin in the middle. It's the same as a kid swallowing one bucky ball - probably does nothing - but if they swallow another, and they attract through tissue, problems.
They can be non-surgically removed prior to MRIs, instead of during.
As for my favorite EM field there is a nearby street with buried powers lines and transformer boxes at ground level. As you walk the street to the main street each box has a bigger EM sphere and I like to let my hand coast over each sphere. It isn't a sphere per say, but only in the sense that at at certain depth in the field the density (for lack of a better term) becomes high enough that I can feel it and it is like a boundary line
Personally I would be looking for a small microchip that could be charged externally and is able to interact with other devices. Potential applications:
* Some form of key storage where computation can be performed. Not just credit cards, passwords, but something more versatile and expandable.
* Connection to devices or hardware for personalisation, i.e. you could indicate to any car you drive your personal preferences, or where to query them. More day-to-day for tech people would be using a colleague's computer and having your mouse sensitivity preferences transferred, editor shortcuts available, etc.
* Constant health monitoring (movement, glucose, VO2, etc). We can get these things from watches and patches, but we ultimately have to take them off at some point to charge and to let our skin breath.
Ultimately, for most people the question that needs to be answered is "why would I, an otherwise healthy person, have a surgery with non-zero risk, to insert X? Why would I not just use X device?".
Some kind of low-risk and non-evasive interface to the brain would be a game changer. Some kind of interface to intended muscle actions could be big too, not just for the disabled but for exoskeleton functionality. I can definitely see an exoskeleton (of some kind) help older people remain more mobile (and economically productive) for longer. Normal jobs would have less wear and tear on the body (i.e. building trade, etc).
Or do you just bite down on a bullet?
You just hold your friend's hand real tight.

As for what my mum thinks: she isn't a huge fan. I'd expressed my interest to her prior to getting it put in, and she wasn't entirely for it, but she honestly doesn't seem to care all that much and understands it is something I really wanted.
