Magical Moving MC Cartridge

Yikes! Had a heart-stopping moment this afternoon.

I noticed that my Lyra Delos had a persistent piece of hair hanging off one side of the washi-paper. It had been there for weeks and refused to come off despite all other debris being removed successfully.
I'd had enough and at first tried a wooden toothpick which failed to tease it off. Time to get the blunt instrument - a pair of long-nosed pliers!
As I approached gingerly from the right of the cartridge upon reaching a range of 1cm or so the tonearm suddenly jumped towards the pliers! I was fortunate the arm clip arrested its progress or I'd be looking at a distressed cantilever by now. Immediately, thinking the pliers were magnetised I checked them and found them to be unmagnetised but merely ferrous. Then the penny dropped - the carts internal magnet was the culprit.
Amazing how easily we can be forgetful and "drop clangers" like this :)
Now all I need is a pair of plastic tweezers.... :D
Something to watch out for when you are tempted to clean your cart :)

I'm pleased to say the cart was none the worse for its ordeal and plays perfectly.
