An older name for a field with a [[divergence]] of zero is ''solenoidal''.  This refers to the fact that, according to [[Maxwell's Equations]], the divergence of the magnetic field is zero, and "solenoid" is a traditional term for an electromagnet.

Both of these terms seem to have fallen out of use around 1960. <ref>Page, Leigh, ''Introduction to Theoretical Physics'', Van Nostrand, 1952</ref><ref>Constant, F.W., ''Theoretical Physics'', Addison-Wesley, 1958</ref><ref>Schwartz, M., S.
