Описание: In lesson 2, we will explore the first property of magnets – their ability to attract ferromagnetic substances. A ferromagnetic substance is simply a substance that be attracted to, or pulled by, a magnet. The three most common ferromagnetic elements are iron, nickel, and cobalt. Any object containing one or more of these elements will, to an extent, be pulled on by a magnet. Often these ferromagnetic metals and other elements are combined to form an alloy – a mixture of two metals or a metal and a nonmetal. These alloys will also demonstrate ferromagnetic properties. During this lesson, we will be testing and observing the ferromagnetic properties of a variety of materials.
