Abstract
The invention is directed to a magazine for an apparatus such as a coordinate measuring apparatus. Measuring probes are held in their magazine locations by magnetic forces. Each magazine location is provided with one or more permanent magnets. The holding force of the permanent magnets is neutralized by an individual electromagnet on that magazine location which is involved in an exchange operation. In this way, the measuring probe being held can be easily removed. The magazine can also be for an apparatus such as a machine tool in which case work tools are held at the magazine locations.
