Jul 23, 2019· The magnetic moment also can be defined for a magnetic dipole created by an electric current. In this case, the magnetic moment is equal to the current (I) multiplied by the area within the current loop (s), which can be represented by the equation m = Is. The direction of this moment can be determined by the right-hand rule.
Iron, cobalt, nickel, gadolinium, dysprosium, and alloys containing these elements exhibit ferromagnetism because of a quantum physical effect called. 2 Magnetic Dipoles, Hysteresis, and Core Losses EP c2006. exchange coupling, in which the electron spins of one atom, interact with those of neighboring atoms.
The most important class of magnetic materials is the ferromagnets: iron, nickel, cobalt and manganese, or their compounds (and a few more exotic ones as well). The magnetization curve looks very different to that of a diamagnetic or paramagnetic material.

Mar 29, 2018· EARTH''S MAGNETISM & MAGNETIC DIPOLE .Historically,Thales of Miletus knew that pieces of lodestone or magnetite (black iron oxide a naturally occurring iron ore) could attract small piece of iron . further, the small pieces of iron could themselves acquire this property.
The particular curvey shape of a bar magnet''s magnetic ﬁeld is referred to as a "dipole" ﬁeld since such a magnet has 2 magnetic poles, a "north" pole and a "south" pole. The only real diﬀerence between the two poles is whether or not the magnetic ﬁeld lines start from one or end on one.
Jul 09, 2014· Indeed, the strongest magnets are not made of either iron, cobalt or nickel, but from neodymium and other rare-earth metals. Its electron structure features 7 electrons with parallel spin within each atom. That''s a huge number. Atoms within a .
Surrounding a magnet - there is a zone of influence, the magnetic field, that represents a summation of all of the fields of all of the domains Describe lines of force What the magnetic field consists of, also called lines of flux, the stronger the magnetic field, the more lines of force/flux or the greater the flux density
Apr 24, 2017· Iron, nickel and cobalt have Curie Points of 1,418, 676 and 2,050 degrees Fahrenheit respectively. The temperatures below a Curie Point are referred to as a magnet''s magnetic ordering temperature. Below the Curie Point, the dipoles rearrange themselves from a disordered, nonparallel orientation into an ordered aligned orientation.
Some simple elemental metals- e.g. cobalt, nickel, and neodynium-do have magnetic domains at room temperature, but most don''t. Magnetic domains are generally not the same as molecules. In fact, most of the crystals we''re talking about here, for example pure iron, have no molecules in them.
