Abstract :
Permanent magnetic (PM) devices have many current and potential applications based on advantages in size, cost and simplicity but they suffer from uncertainties related to environmental and damage effects. One missing ingredient is a magnet designed to explicate demagnetization effects as a function of the principal magnetic characteristics of the device, the material, the blocks and their fab procedures - all of which need to be independently varied while minimizing the induced radioactivity from testing. We describe such a magnet and the measurements on it and its blocks and discuss the parameters of most interest as well as the constraints that motivate this choice.
