Next message: George Huxtable: "Re: Historical Magnetic Variation/Declination"
Hello,
I have a small emergency field compass that was kept unused in a pocket on
my mountain bike for the last 10 years. I took it out recently and
discovered it had become very sluggish. I suspect that the magnet under the
compass card has lost much of its power and canot overcome the friction
between the compass card and the needle it floats on. I cannot open it to
get to the needle and clean its tip.
Is there a way to recharge the magnet? I tried placing the compass overnight
on magnetized objects like my phone handset or a large screwdriver but I
suspect I need a stronger source of magnetic field. A 220V wire leading to
an operating house appliance perhaps?
Any advice would be much appreciated.
