Principle
A conductor loop carrying a current in an uniform magnetic field experiences a torque. This is determined as a function of the radius, of the number of turns and the current in the conductor loop and of the strength of the external field.
Benefits
- Particularly homogeneous magnetic field and high flux density due to large Helmholtz coil diameter
- Torsion dynamometer offers highly precise measurements
Tasks

- of the strength of the magneticfield,
- of the angle between the magnetic field in the magnetic moment
- of the strength of the magnetic moment.
Learning objectives
