The atoms in ferromagnetic materials act like small magnets (due to currents within the atoms) and can be aligned, usually in millimeter-sized regions called domains Magnetism is a subject that includes the properties of magnets, the effect of the magnetic force on moving charges and currents, and the creation of magnetic fields by currents

There are two types of magnetic poles, called the north magnetic pole and south magnetic pole North magnetic poles are those that are attracted toward the Earth’s geographic north pole

meter — common application of magnetic torque on a current-carrying loop that is very similar in construction to a motor; by design, the torque is proportional to I and not θ , so the…. north magnetic pole — the end or the side of a magnet that is attracted toward Earth’s geographic north pole. south magnetic pole — the end or the side of a magnet that is attracted toward Earth’s geographic south pole. ferromagnetic — materials, such as iron, cobalt, nickel, and gadolinium, that exhibit strong magnetic effects.
