Fig. 1.

Experimental setup. The metallic cylinders are suspended from a balance and placed in the nonuniform magnetic field created by a solenoid. When the magnetic field is switched on, the magnetic force is measured by a differential reading on the balance.

The loops used in the calculation of the (a) induced electric field and (b) the magnetic field associated with the eddy currents.

(a) The force measured with the balance for massive cylinders for various radii. Lines correspond to linear fits, (b) the equivalent diamagnetic susceptibility depends on the fourth power of the cylinder’s radius [see Eq. (12)]. In both plots the largest error bars are only slightly larger than the symbol size and are not shown.

Fig. 4.

(a) The force measured with the balance for hollow cylinders for various radii. The wall thickness is . Lines correspond to linear fits, (b) the equivalent diamagnetic susceptibility depends on the third power of the radius [see Eq. (20)]. The largest error bars are only slightly larger than the symbol size and are not shown.
