[Surnetkids] Magnetism

Dear Reader,

Today’s Magnetism topic is in honor of Hans Christian Ørsted’s birthday, 14 August 14, 1777. Ørsted (1777 — 1851) was the Danish physicist and chemist who discovered that electric currents create magnetic fields. His work led to understanding the connection between electricity and magnetism.

Magnetism is a force that attracts and repels things. It is the result of the movement of charged particles. Although the theoretical concept may sound difficult, it is easy to demonstrate to even young children with very simple experiments. Nickel and iron are two metals easily effected by magnetic forces (they are attracted to magnets) while copper and aluminum are not (and can not be magnetized.)

Cool Magnet Man

Electrical engineer Rick Hoadley (a.k.a. Cool Magnet Man) shares his magnetic enthusiasm with this virtual textbook and dozens of experiments that you can either buy or build. “Some of the experiments are very basic – things you’ve done since second grade. Others are unique; perhaps you hadn’t thought of doing some of these before, or had difficulty in trying to set them up.” Chapters that include experiments are marked with a yellow “Expt” button.

Exploratorium: Magnetism Snacks

Exploratorium Snacks are not the kind you eat after school, but rather experiments you can do at home or in a classroom. This collection includes a dozen Magnetism Snacks arranged in alphabetic order from Circles of Magnetism (use a 6-volt lantern battery to create a magnetic field stronger than the earth’s) to Stripped Down Motor (an electromagnetic coil of wire spins when it interacts with a permanent magnet.) More science snacks, such as chemistry, color, and sound experiments, can be found on the Snacks by Subject page.

Hyper Physics: Magnetic Fields

“Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits.” This illustrated chapter from the Hyper Physics textbook (hosted by the physics department at Georgia State University) explains magnetic fields for high-school and college students. Unlike a linear printed textbook, however, there are lots of links to help you explore related concepts.
