They are not couloumbs, you got your fields mixed!

A nice way to visualize both magnetic and electric fields
is as differential forms. The H field is a one-form,
the B field is a two-form. Similarly the E field is
a one-form and the D field a two form. Download the
the papers at http://www.ee.byu.edu/ee/forms/forms-home.html
for some examples.
