What is the inverse triangle symbol represent?

  1. Mar 11, 2013 #1
    1. The problem statement, all variables and given/known data
    B=magnetic flux density . A is the vector potential of magnetic field. How to get the formula B=∇A


    2. Relevant equations
    http://en.wikipedia.org/wiki/Magnetic_moment


    3. The attempt at a solution
    B=magnetic flux density . A is the vector potential of magnetic field. B=A/(area that is normal to the magnetic field). But how to get the area??
    Guide will do. Thank you

    This is the differential operator called del:

    If you are studying magnetic fields, you will also have to study some vector calculus.
