There was a lot of good physics in this experiment that I probably did last with my students in the late nineteen sixties. We did it with the aid of a ballistic galvanometer; today a modern integrating instrument would be used.

Rowland's Ring is a device for tracing out
curves of magnetic induction as a function of magnetizing field for an iron
ring; these curves are called hystersis curves. It was developed by
Henry Augustus Rowland (1848-1901).

The apparatus is in the Greenslade Collection and came to me from Carroll
College in Wisconsin. The Gaertner Scientific Corp. of Chicago sold it for
$17.50 about 1930. The next time I photograph it I will do a better job of
removing the accumulated dust!
