[X-Men/X-Men CU] Did the Nazi's perform any experiments on Magneto when his powers firstmanifested themselves in Auschwitz? If so, what?

Just saw the opening scene of the first X Men movie again for the first time in years and it made me wonder. They were pretty gung-ho about experimenting on weird/unique people, so I was a wondering if they did anything to him, and what.

If this cannot be answered within the Cinematic Universe, i'd be interested to know if this was ever explored in the comics.

In the movies, they show more about what happens in *First Class*, though they don't detail his escape it's assumed that he leaves before much is done to him, personally.

In the comics, his family lives in Germany until 1939, when they move to Poland and get captured. His family is killed, but he spends a long time in Auschwitz, working as part of a slave group clearing bodies from the gas chambers. Aware that, as witness to Nazi crimes, they would be put to death themselves, the Sonderkommando of Birkenau Kommando III staged an uprising on October 7, 1944, during which Max Eisenhardt and the Romani girl Magda escaped. 

They moved to Ukraine and had a daughter, and Eisenhardt adopted the name Magnus. His powers were discovered, and an angry mob burned down his home and killed his daughter. His pregnant wife left, later bearing his twin children Scarlet Witch and Quicksilver, before she died.

Eisenhardt changed his name to Erik Lehnsherr, and soon ran into Charles Xavier. His discussions with Xavier crystallized his views, and he realized they were incompatible. So he left and started working towards protecting Homo superior from the inferior (but numerous) people around them.
