This paper proposes a linear eddy-current feature to determine the radius of a metallic ball in a non-contact manner. An electromagnetic eddy-current sensor with two coils is placed co-axially to the metal ball during measurement. It is well known that the distance between the sensor and test piece (i.e. lift-off) affects eddy-current signals.

Ball bearings of different radius were dropped from rest into the glycerol and timed over 10 cm intervals until a constant time reading was achieved. At this point a=0 and therefore terminal velocity was achieved. From the results, it was decided that ball bearings of radius 5.81mm and below should be chosen for the investigation.
