What is meant by hysteresis? Hysteresis is a term applied to rapid magnetization and demagnetiza-tion of a soft iron core lying within a coil of insulated wire, through whichan automatically interrupted galvanic current is passing. 46 THE KLECTRO-THERAPEUTIC GUIDETHE PRIMARY COIL What is a primary coil? A primary coil is one of coarse wire, wound about a cylinder, called ahelix, through which a galvanic current is caused to pass interruptedly forthe purpose of inducing hysteresis in a bundle of soft iron rods within thehelix, called a Thus we see, by the accompanying sketch, where a bundle of iron wiresis immersed in a primary field. This bundle of iron wires, insulated fromthe coil of wire, is called a core. The wire so wound about the core iscalled the primary coiV. How is induction modified?
