Principle
A magnetic field of variable frequency and varying strength is produced in a long coil. The voltages induced across thin coils which are pushed into the long coil are determined as a function of frequency, number of turns, diameter and field strength.
Benefits
- Huge field coil for homogenous magnetic field
- On-the-fly switching of the numerous induction coils
- Easy frequency setting thanks to digital function generator
Tasks
- Determination of the induction voltage as a function
- of the strength of the magneticfield,
- of the frequency of the magneticfield,
- of the number of turns of the induction coil,
- of the cross-section of the induction coil.
