STUDY. Magnetism is a class of physical phenomena that are mediated by magnetic fields.

Magnetic field – the region around a magnet that exerts themagnetic force.

SECTION 3 Magnetism Main Idea Like magnetic poles repel each other and unlike poles attract each other. In words, the curl (or circulation) of the magnetic field is equal to the current density. In 1269, Peter Peregrinus de Maricourt wrote the Epistola de magnete, the first extant treatise describing the properties of magnets. Magnetism. Start studying Chapter 7, Section 1-3 Magnetism and its Uses. Magnets The name magnet comes from the region of Magnesia which now modern day Greece The first magnetic rocks called Lodestones were found in this region almost 3000 yrs ago.

Lightning in a Bottle These lacy streamers in the plasma globe and lightning have some- thing in common. A lodestone is composed of an iron-based material called magnetite . Chapter 17: Magnetism and Its Uses. However, other types of magnetism can be stronger than diamagnetism, so it is only observed in materials that contain no unpaired electrons.

The magnetic fieldweakens with distance . Section 3: Producing Electric Current. Chapter 17: Magnetism and Its Uses. Interaction between two magnets called magnetic force increases. They are sparks, caused by the rapid movement of electric charges. The main types of magnetism are: Diamagnetism: All materials display diamagnetism, which is the tendency to be repelled by a magnetic field. Amp`ere’s Law, in its most general form, is one of Maxwell’s equations of electro-magnetism: in a steady electrical field, ∇×H = Jf,whereJf is the electric current density (see Section A.3.6 in the appendix for review of the ∇ operator). Magnetic poles as magnets move closer together. Here, the charges move from the metal ball in the center to the inner wall of a surrounding glass ball. Current Flow. It can be an electric current in a conductor or charged particles moving through space, or it can be the motion of an electron in an atomic orbital. Section 1: Magnetism.
