If someone wants to, they can easily find a series of formulas describing magnetic moment. However, mathematical calculations are usually not necessary for anyone; what matters more is understanding the phenomenon itself. To define magnetic moment, we should start by acknowledging that numerous objects in our world are magnets. Starting from the smallest, invisible to the naked eye, electrons and atoms, through chunks of magnetite, and man-made magnets, all the way to our entire planet. Which, as it turns out, is a massive, powerful magnet from which we and plants and animals benefit. Each of these objects possesses a magnetic field that spreads between its poles in the form of lines. If some physical object is placed in such a field and begins to rotate under the influence of forces acting on it, we then say it has a magnetic moment. In practice, this moment depends on the force acting on the dipole, or rather, the torque. If the lines of the object align with the lines of the field in which the object was placed, it will remain motionless. This can be best illustrated by a simple compass needle. Because it is magnetized, it aligns itself along the Earth's magnetic lines; if deflected, it will move until it achieves stability.
