Magnetic Strength

  1. Feb 2, 2007 #1
    If a magnet is cut into exactly 2 equal parts , the magnetic strength of this part is half the magnetic strength of the original magnet.



    Why does it get halved. What is the formula for magnetic strength>?
    What is meant by uniform magnetic field?

    Again, please show you've thought about the question

    magnetic moment=pole strength*distance between poles.

    Is it the quation i was looking for?

    The magnetic strength is determined by the amount of contributors (atoms with certain electronic configurations) to the magnetic field of the magnet. If the magnet is cut in half each of the halves will get approximately half of the original amount of contributors.

    This equation is indeed true. So when distance b/w poles gets halved so does the magnetic moment!
