The Magnetic Monster is a 1953 independently made American black-and-white science fiction film, produced by Ivan Tors and George Van Marter, directed by Curt Siodmak and (uncredited) Herbert L. Strock.

[2] The Magnetic Monster marked Carlson's initial foray into science fiction and horror films; he would follow it with It Came from Outer Space (1953), The Maze (1953), Riders to the Stars (1954), Creature from the Black Lagoon (1954), and such TV series as Thriller and Voyage to the Bottom of the Sea.

OSI officials determine that, with its rate of growth, it will only be a matter of weeks before the isotope becomes heavy enough to affect the Earth's rotation on its axis, eventually causing it to break out of its orbit around the Sun.

Stewart hypothesizes that the isotope could be "overfed" and bombarded with enough energy to cause it to fission into two separate, stable elements, but computer calculations indicate that this process would require nearly one gigavolt of electricity.

For the Deltatron, the film used ten minutes of footage of the atom smasher from the German science fiction thriller Gold (1934), directed by Karl Hartl and produced by UFA.
