Abstract
At the National Institute of Standards and Technology a new watt balance, NIST-4, is currently being designed. This apparatus will be used to realize the base unit of mass after the redefinition of the SI has taken effect. As a realization device, NIST-4 is designed to be easy to use with low maintenance. To meet these requirements we decided to use a permanent magnet system to generate the magnetic flux. A brief overview of the permanent magnet system is given.
