Magnetism 1. Which of the following does not create a magnetic field?
... D) Yes; the domains in the iron are induced into alignment and one pole is attracted to the magnet. 13. You have an unmagnetized piece of iron. A) Dropping it repeatedly will cause the domains to line up, magnetizing the object. B) Stroking it with a permanent magnet will align the domains and magne ...

Magnetic monopole
A magnetic monopole is a hypothetical elementary particle in particle physics that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). In more technical terms, a magnetic monopole would have a net ""magnetic charge"". Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence.Magnetism in bar magnets and electromagnets does not arise from magnetic monopoles. There is no conclusive experimental evidence that magnetic monopoles exist at all in our universe.Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.
