Electronic Principles The core of an electromagnet is said to be in saturation when: changing the polarity of the current in the coil changes the polarity of the magnetic field around the core None of these the core is permitted to move freely within the coil frequent changes in the direction of current through the coil causes heating effects in the core material 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 the core is permitted to move freely within the coil frequent changes in the direction of current through the coil causes heating effects in the core material an increase in current through the coil causes no further increase in the mmf ANSWER DOWNLOAD EXAMIANS APP
