What’s your experience with “sensing?”
Well in my opinion there are two ways you sense stuff:
#1 Electromagnetic field change sensing:
Thats what you sense from stuff like microwaves, electro motors and powersupplys.
I sense that kind of stuff every day, mostly my pc fan and powersupplys i get close to.
I also feel most of my powertools while using them. its a funny little new sense.
Once i found a pool pump in the trash, i plugged it in and it felt like i got a electric shock so i threw that thing away and unplugged it. after dissasembling it i saw that there is a short on two 220v wires and i felt that, that was amazing 
#2 Sensing of ferromagnetic materials.
If i touch materials that are ferromagnetic (like iron) i can sense that and i can feel differences between diffrent types of iron.
its also a nice useful adition.
Lifting strengths between the different models?
The Xg3 V2 lifts the most, followed by the V1 and then comes the titan. but thats logically if you compare the sizes of the Xg3 to the Titan.
Do you ever have something “snap” onto your biomagnet that you don’t want? If so does that hurt, cause bruising, etc?
Yea, if i have coins on my table they sometimes attach to my magnets. it does not hurt but in the beginning it feeled strange.
i never got bruising from objects snapping to my magnets.
How long for necrosis to take place if an object was held to the skin. Would small electronic screws cause this?(my desired use is to hold small screws with it, have my hand be a built in magnet tray.) Especially if they’re only being held there for a few minutes?
I get skin deformation and blood flow issues at about 10 minutes when something is permanently attached.
i had stuff on there longer by accident (was on a roadtrip concentrated on the traffic and forgot that i picked up a paperclip)
at some point i itched the location and noticed it - it was about 40 mins on there but everything recovered.
And just generally, what’s your opinion on your biomagnets?
I love them!!!
im so much in loved with subdermal magnets that i started building my own.
im mostly in love with the xg3 v2 because its lifting power. i have 4 of them at home and currentl 2 installed.
The titan is also amazing because it will just last forever and is indestructable!
