Magnetic flux has the dimension mass length squared per time squared electric current.  The SI derived unit of magnetic flux is the weber, which is defined as a volt second.

Maple knows the units of magnetic flux listed in the following table.

An asterisk ( * ) indicates the default context, an at sign (@) indicates an abbreviation, and under the prefixes column, SI indicates that the unit takes all SI prefixes, IEC indicates that the unit takes IEC prefixes, and SI+ and SI- indicate that the unit takes only positive and negative SI prefixes, respectively.  Refer to a unit in the Units package by indexing the name or symbol with the context, for example, weber[SI] or Mx[standard]; or, if the context is indicated as the default, by using only the unit name or symbol, for example, weber or Mx.

The units of magnetic flux are defined as follows.

An abweber is defined as $1.\times {10}^{\mathrm{-8}}$ weber and is energy-equivalent to the unit square root dyne centimeter ($\sqrt{\mathrm{dyne}}\mathrm{cm}$).

A statweber is defined as $1.\times {10}^{\mathrm{-6}}c$ weber where c is the magnitude of the speed of light, and is energy-equivalent to the unit square root dyne second ($\sqrt{\mathrm{dyne}}s$).

A maxwell is another name for an abweber.

A unit_pole is defined as $1.256637062\times {10}^{\mathrm{-7}}$ weber.
