... We can visualize the Earth’s magnetic field as being produced by a giant bar magnet within the Earth. What we call the “North geographic pole” corresponds to the “south pole” of the imaginary bar magnetic so that the north needle on a compass points towards the north geographic pole! ...

... Properties of Electromagnets • One end of the electromagnet is a north pole and the other end is a south pole. • If placed in a magnetic field, an electromagnet will align itself along the magnetic field lines, just as a compass needle will. ...

Activity Lesson Plan
... 1. Make the iron filing demos3. Refer to Figure E&M_2_1 during the construction of these demo materials. Try to pick sturdy paper plates so that the students can handle them easily without destroying them. Chinet plates work well. If the plates do not fit inside the resealable plastic baggies, cut ...

Magnetic Force - Rutgers Physics
... According to Oersted, when two ends of a battery are connected by means of a metal wire, an "electric conflict" is produced in the conductor and the surrounding space, causing the magnetic needle to be deflected. In the same article, Oersted also stated that "the pole below the point through which t ...

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.
