panying magnetization increases rapidly with increase of field. 
The changes in the lower fields are so small that a very small 
component of longitudinal magnetization is apparently sufficient 
under certain circumstances to counterbalance the decrease due to 
the transverse effect. If this be the explanation of the maximum 
obtained in certain cases, then it follows that the transverse effect 
preponderates greatly in the higher fields.
