PHYWE Study of hysteresis of ferromagnetic materials Cobra SMARTsense

Principle A magnetic field is generated in a ring-shaped iron core by means of a continuous, adjustable direct current applied to two coils. The field strength Η and flux density B are measured and the hysteresis is recorded. The residual magnetization and coercivity of two different iron cores can be compared. Benefits Simple experimental setup and intuitive software operation: better results in less time Added value through data logging: direct visualization Learning Objectives Tasks Record the hysteresis curve for a solid iron core and for a laminated iron core. Learning Objectives Induction Magnetic flux Coil Magnetic field strength Magnetic field of the coils Residual magnetization Coercivity of the field Software included. Computer not included.
