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.
