Principle:
A beam of potassium atoms generated in a hot furnace travels along a specific path in a magnetic two-wire field. Because of the magnetic moment of the potassium atoms, the nonhomogeneity of the field applies a force at right angles to the direction of their motion. The potassium atoms are thereby deflected from their path. By measuring the density of the beam of particles in a plane of detection lying behind the magnetic field, it is possible to draw conclusions as to the magnitude and direction of the magnetic moment of the potassium atoms.

Tasks:
1. Recording the distribution of the particle beam density in the detection plane in the absence of the effective magnetic field.

2. Fitting a curve consisting of a straight line, a parabola, and another straight line, to the experimentaly determined special distribution of the particle beam density.

3. Determining the dependence of the particle beam density in the detection plane with different values of the non-homogeneity of the effective magnetic field. 4. Investigating the positions of the maxima of the particle beam density as a function of the non-homogeneity of the magnetic field.

4. Investigating the positions of the maxima of the particle beam density as a function of the non-homogeneity of the magnetic field.
