Ferromagnetic hysteresis with Cobra3
P2430711
Hysteresis for a massive iron core.
Principle A magnetic field is generated in a ring-shaped iron core by a continuous adjustable direct current applied to two coils. The field strength Η and the flux density B are measured and the hysteresis recorded. The remanence and the coercive field strength of two different iron cores can be compared.
