Hi, my name is belejit and i just began using comsol for simulation. I am trying to plot the gradient of an array of magnets. please anyone got an idea?

This is confusing to me. Usually I think of a gradient as a differential operator operating on a scalar field, yielding a vector field. Such as E=-grad phi. www.physicsforums.com/showthread.php?t=12392

The magnetic field is already a vector field...

Please explain more clearly what you are trying to calculate.

Hi Belejit,

The following blog post discuss the technique to plot the gradient of Magnetic Fields.
