Hello guys!
I found this interesting little thingy when i was dismantling a Laser Printer toner cartridge:

It is magnetic and can "stick" onto metallic surfaces really well. As you can see, it is 23 cm / 9 inch long, and as you cannot see, it is 7.5mm / .295 mill thick.
Does anyone has any experience with these things?
Can i use this to make a DIY pinpointer?
