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

Determination of the torque due to a magnetic moment in a uniform magnetic field, as a function

1. of the strength of the magneticfield,
2. of the angle between the magnetic field in the magnetic moment
3. of the strength of the magnetic moment.

What you can learn about
