Principle
Current-carrying coils have a magnetic field around them which resembles that of a bar magnet. Inside the coil, the magnetic field lines are parallel to the axis of the coil. The direction of the field depends on the direction of the current in the coil. The magneti ...
Magnetism is a phenomenon that can be attributed to electromagnetic interaction. It manifests itself through the force that acts on magnetisable material and moving electric charges. The force is hereby conveyed via a magnetic field. Measurement is ma ...
A nickel, tungsten or bismuth rod is brought between the faces of pole pieces 06493-00, attached to U-shaped magnet 06320-00. Rods made of paramagnetic or ferromagnetic materials align themselves parallel to the lines of the magnetic field, whereas ones made of ...
Magnetic hysteresis is a non-linear relationship between magnetic flux density B and magnetic field strength H. Characteristic properties of a ferromagnetic material can be determined from the hysteresis loop.
How is it possible, that the fuel / air mixture of a spark ignition engine can be ignited by a voltage of up to 30,000 V, but the car battery only supplies 12 V? We will get to the bottom of this phenomenon in this experiment. When the magnetic field ...
A constant magnetic field, its magnitude and direction known, is superimposed on the unknown earth magnetic field. The earth-magnetic field can then be calculated from the magnitude and direction of the resulting flux density.
Tasks
The magnetic field along the axis of wire loops and coils of different dimensions is measured with a teslameter (Hall probe). The relationship between the maximum field strength and the dimensions is investigated and a comparison is made between the measured and the ...

A current which flows through one or two neighbouring straight conductors produces a magnetic field around them. The dependences of these magnetic fields on the distance from the conductor and on the current are determined.
Determ ...
A current which produces a magnetic field is passed through an electrolyte.This magnetic field inside the conductor is determined as a function of position and current.
Determination of the magnetic field inside a conductor as a f ...
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 di ...
