For a current loop, this definition hints at the magnitude of the magnetic dipole moment corresponding to the product of the current times the region of the loop. This definition is based on the principle, of measuring the magnetic moment of an unknown sample. Where τ is the torque acting on the dipole, B is the outside magnetic field, and m is on the magnetic moment. It can be defined as a vector linking the aligning torque on the object from an outside applied magnetic field to the field vector itself. The magnetic moment can also be considered, so, to be a vector. The direction and strength of this torque depend not only on the degree of the magnetic moment but also on its location relative to the direction of the magnetic field. The same applied magnetic field generates larger torques on objects with bigger magnetic moments. The magnetic dipole moment of an object or thing is readily defined in relation to the torque that the object experiences in a certain magnetic field. Higher-order expressions (such as the magnetic quadrupole moment) can be needed in addition to the dipole moment for prolonged objects. The magnetic dipole component is enough for small adequate magnets or for large sufficient distances. Examples of such objects that have magnetic moments contain loops of electric current (like electromagnets), elementary particles (such as electrons), permanent magnets, various molecules, and several astronomical objects (such as various planets, certain moons, stars, etc).Įxactly, the word magnetic moment normally denotes to a system's magnetic dipole moment, the component of the magnetic moment that can be denoted by the same magnetic dipole: magnetic north and south pole divided by a very minor distance. It is the magnitude that signifies the magnetic orientation and strength of a magnet or other object that creates a magnetic field.
