  • Query for Tim#1

    Dear Tim,
    I did a double-take on your finished project, the torsion fibre magnetometer. I could use some thing similar for research, probably not so sensitive, are they difficult/expensive to make?

    Where is this device to be found? I'm interested because when coronal mass ejections hit the earth's magnetosphere it can deflect the magnetic field by as much as +- 1/2 degree. This often means good auroral activity and I like to take pictures of aurora. It would make a good aurora alarm.
