About This Product
Passing current through the series-connected windings magnetises the U-shaped soft iron core, which then holds the flat-ground armature. With 1 A flowing, a force of about 75 N is needed to pull the armature away from the core. The recommended working current is 5 A, and the maximum is 8 A. The Electromagnet is available for supply within India and for export to Turkmenistan, Iran, Ghana, Morocco and Philippines.
Frequently Asked Questions
