[Paraview] "mag" what is the meaning of it?

[Gang]

              Hi everyone,

   I have a question about the Interface of the Paraview3.3.0（development）.

   In the Properties tab, there is a Apply Displacements checkbox, following it, there is a mag .


   Know little about it , and search it on the net, helpless....

   can someone give any explanation?

   thanks
