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.

Benefits

  • Simple experimental setup and intuitive handling of the software: Better results in less time
  • Added value due to the use of datalogging: Direct visualisation of the learning objective

Tasks

Record the hysteresis curve for a massive iron core and for a laminated one.

Learning objectives

  • Induction
  • Magnetic flux
  • Coil
  • Magnetic field strength
  • Magnetic field of coils
  • Remanence
  • Coercive field strength
