Electricity & Magnetism The World’s Simplest Motor Ideal for introducing students of any age to electricity and magnetism, this easy-to-use kit is priced so you can give all your students a hands-on first step into technology. By building and observing a motor that converts electrical energy into motion, students discover and explore first-hand several key properties of electricity and magnetism. Set-up is a snap. Current supplied by a D battery (sold separately) creates a magnetic field around the coil, causing the coil to push away from the ceramic magnet in the base and spin as long as current is present. P8-8300 04-2106 P8-8300-01 Motor 10 or more D Batteries, 2/pk. Replacement Wire, 5/pk. $4.95 $4.50 each $1.50 $2.75 Show how electric currents and magnets can exert forces on each other. Watch how slowly the magnetized plug drops through the tube! Lenz’s Law Apparatus Experience the fundamental principle behind electric motors with this demonstration. Drop the strongly magnetized plug through the copper pipe, and induced currents cause it to fall very slowly. The unmagnetized plug falls without resistance. Viewing window lets you see the action. Experiment and information included. Demonstrate electric and magnetic forces. Electric current generated by a moving magnet will always oppose the original motion of the magnet that created the current. P8-8400 P8-1153 Amusement Park thrill rides use this same principle for braking. Magnetic Terminal This new, clever solution simplifies building battery circuits. Magnetic Terminal scissor open to hold bare wires (or alligator clips) neatly and securely to the ends of C or D cells. P6-1410 Magnetic Terminal 20 or more $1.25 $.95 each Lenz’s Law Apparatus Magnetic Field Viewing Film, 9" x 7.2" $18 $19 Discovery Pack Electricity & Magnetism Discovery Pack Understand the important relationship between electricity and magnetism — and how one can produce the other — with this collection of equipment and activities. Lenz’s Law Apparatus Dynamo Flashlight World’s Simplest Motor Magnet Wire Spool Clear Compasses, 20/pk. Giant Neodymium Magnet 3 Japanese Yen Coins Galvanometer, 500 μA Ceramic Ring Magnet, Small Instruction & Lesson Ideas P6-2500 $99 Electromagnetic flashlight with clear barrel lets students see how a moving magnetic field creates current Look inside the clear case as you shake, and see the powerful magnet pass back and forth through a loop of wire. Electrical energy is stored in a capacitor that can be charged hundreds of thousands of times. The “bulb” is an ultra-bright white LED. 30 seconds of shaking provides a full charge, and will produce a beam of light for several minutes. Use this to wrap up and review many concepts 30 seconds in your unit on of shaking electricity and provides magnetism! a full charge, and will produce Size 6.5". a beam of light for P6-6052 several minutes.
