In my experience, the electromagnet appears to draw less current when
latched to the metal plate.  This is an unscientific observation based upon
the temperature of the magnet increasing when not latched to the steel
plate.  Amazing that they can generate such a strong holding force using
three watts of power as long as the two parts perfectly mate to each other.
