WebJan 9, 2024 · Magnetic North is so-called to distinguish it from True North. In other words, it is a location, not its magnetic polarity. It's magnetic polarity, however, is south as it attracts the north magnetic pole of a magnet or compass needle.
WebThe 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). WebMagnetic striping and polar reversals Beginning in the 1950s, scientists, using magnetic instruments (magnetometers) adapted from airborne devices developed during World War II to detect submarines, began recognizing odd magnetic variations across the ocean floor.
WebIf the magnet is withdrawn from the coil upper end acquires south polarity, so work is done against the force of attraction. Now we know that as the magnet moves through the coil magnetic flux linked with the coil changes inducing a current. The direction of the induced current is found from Lenz' law as follows. http://www.magnetictherapymagnets.com/magnetic-polarity-magnets.html
