Definition that contains magnetic pole
- true determined with reference to the earth's axis rather than the magnetic poles
- ross British explorer of the Arctic and Antarctic; located the north magnetic pole in 1831; discovered the Ross Sea in Antarctica; nephew of Sir John Ross (1800-1862)
- oersted the magnetic field strength 1 cm from a unit magnetic pole
- magnetic monopole a hypothetical particle with a single magnetic pole instead of the usual two
- sir james clark ross British explorer of the Arctic and Antarctic; located the north magnetic pole in 1831; discovered the Ross Sea in Antarctica; nephew of Sir John Ross (1800-1862)
- bar magnet a magnet in the form of a bar with magnetic poles at each end
- james clark ross British explorer of the Arctic and Antarctic; located the north magnetic pole in 1831; discovered the Ross Sea in Antarctica; nephew of Sir John Ross (1800-1862)
- dipolar having equal and opposite electric charges or magnetic poles having opposite signs and separated by a small distance
- magnetic needle a slender magnet suspended in a magnetic compass on a mounting with little friction; used to indicate the direction of the earth's magnetic pole
- coulomb's law a fundamental principle of electrostatics; the force of attraction or repulsion between two charged particles is directly proportional to the product of the charges and inversely proportional to the distance between them; principle also holds for magnetic poles
