Magnetism Flashcards
the word magnetism comes from the name of that amount village named ___
Magnesia
it is the properties and interactions of magnets
Magnetism
3 principal types of magnets
natural magnet
artificially produced permanent magnets
electromagnets
in three types of magnets, its best example is the earth itself, because it spins on an axis
natural magnet
in three types of magnets, it is available in many sizes and shapes but principally as bar or horseshoe-shaped magnets, usually made of iron
artificially produced permanent magnet
in three types of magnets, it consists of a wire wrapped around an iron core
electromagnets
3 magnetic states of matter
diamagnetic
paramagnetic
ferromagnetic
in three magnetic states of matter, this cannot be magnetized and they are not attracted to a magnet
diamagnetic
in three magnetic states of matter, its materials lie somewhere between ferromagnetic and non-magnetic and they are slightly attracted to a magnetic field
paramagnetic
in three magnetic states of matter, this can be easily magnetize and can be usually be permanently magnetized by exposure to a magnetic field
ferromagnetic
nonmagnetic ; wood and glass
diamagnetic ; ___ and ___
paramagnetic ; gadolinium
ferromagnetic ; iron, ___ and ___
nonmagnetic ; wood and glass
diamagnetic ; water and plastic
paramagnetic ; gadolinium
ferromagnetic ; iron, nickel and cobalt
3 magnetic laws
magnetic dipoles
magnetic induction
magnetic force
in three magnetic laws, it is where every magnet no matter how small has two poles
magnetic dipoles
in three magnetic laws, it is where imaginary magnetic field lines are called magnetic lines of induction and the density of the lines is proportional to the intensity of the magnetic field
magnetic induction
in three magnetic laws, it is similar to electrostatic and gravitational forces that also are inversely proportional to the square of the distance between the objects under consideration
magnetic force
