There are two incidents being thrown about here.
The first is the incident from the Black Galaxy Saga, circa Thor 420 or so.
Without giving away the details of the Black Galaxy Saga(its one of the most important in Marvel Cosmic continuity), someone wanted to destroy the Black Galaxy. They made a Null Bomb. The bomb detonated but Thor (using Mjollnir)
a) absorbed the energy
b) perceived hundreds of billions of light years away in another galaxy that the star that some random civilization was orbiting was dying
c) sent said energy across hundreds of billions of lightyears
d) used it to restore the star to its older, higher level output
The second incident is the Incident from an Avengers annual, 16 IIRC.
In that the Grandmaster, for some plot based reason, wanted to blow up the universe. He made 5 Nega Bombs (IIRC this is what they were called). Each would destroy 1/5 of the universe. One in fact did go off and blow up 1/5 of the universe (it must not have been an important part).
I don't recall what happened to the other 3, but they did not go off. The 5th one did. Thor created a forcefield which contained the blast and then IIRC shunted the energy into another dimension.
As to Thor vs Magneto, as someone mentioned above, Thor has owned him in the past, including an incident where he depowered him.
Thor would kill Magneto in seconds here.
