Magnetic moment in the magnetic field

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,
