Magnetic pole physics Britannica
WebA magnet can exert a force on another nearby magnet. Magnets have two poles: a north pole a south pole The magnetic force is strongest near the magnet's poles. The rules of magnetism... The north magnetic pole, also known as the magnetic north pole, is a point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it will point straight down). There is … Ver mais All magnets have two poles, where the lines of magnetic flux enter and emerge. By analogy with Earth's magnetic field, these are called the magnet's "north" and "south" poles. The north-seeking pole of a magnet was defined to have … Ver mais Early European navigators, cartographers and scientists believed that compass needles were attracted to a hypothetical "magnetic island" somewhere in the far north (see Rupes Nigra), or to Polaris, the pole star. The idea that Earth itself acts as essentially a giant … Ver mais Historically, the magnetic compass was an important tool for navigation. While it has been widely replaced by Global Positioning Systems, many airplanes and ships still carry them, as do casual boaters and hikers. The direction in … Ver mais Over the life of Earth, the orientation of Earth's magnetic field has reversed many times, with magnetic north becoming magnetic south and … Ver mais First observations The first group to reach the north magnetic pole was led by James Clark Ross, who found it at Cape Adelaide on the Boothia Peninsula on … Ver mais As a first-order approximation, Earth's magnetic field can be modeled as a simple dipole (like a bar magnet), tilted about 10° with respect to Earth's rotation axis (which defines the geographic north and geographic south poles) and centered at Earth's center.
