Electronic Principles
The core of an electromagnet is said to be in saturation when:

frequent changes in the direction of current through the coil causes heating effects in the core material
the core is permitted to move freely within the coil
an increase in current through the coil causes no further increase in the mmf
changing the polarity of the current in the coil changes the polarity of the magnetic field around the core
None of these
