    Hi everybody!
    I am Pranab. I would like to know the direction bar magnet would point to, if it is taken to outer space and freely hung.

    Interesting question... can't wait to hear some answers.

    How does a magnet work in space? Does it still have magnetism? Does it travel towards the neareast other magnet at mega speed?

    I thought that they did this in the space shuttle? I believe that the magnet aligned itself with the earth's magnetic field.

    Ok that's interesting. I wonder what altitude that was? What happens when the magnet is nowhere near Earth? this might be a way to see where the earths magnetic field ends?

    The earth's magnetic field does not abruptly end, it just gets weaker with distance. At some point, it would be too small to measure.
