A good example of an experiment developed to realize the SI base unit of current is the ampere balance [6].
The most important weakness of the ampere balance experiment is its reliance on measurements of coil geometry-determining /3 is the limiting factor of the experiment.
If the force coil of an ampere balance is moved at constant speed v through the magnetic flux gradient produced by the second coil, then a voltage V is induced across it.
