This is for showing A.C. on an oscilloscope or meter or for demonstrating the use of a dynamo in lighting a lamp. This apparatus has a cycle dynamo mounted on a base. Two 4mm socket terminals are provided for the dynamo output, connected in parallel with an M.E.S. lamp holder and 2.5V bulb.
Using a sphere with an embedded alnico magnet, students will be able to create a mini-magnetic field and learn about the Earth's magnetic core. Iron filings included in kit will help students locate magnetic poles and observe the effects of a magnetic field. Includes Teacher's Guide.
EISCO's Bridge Rectifier Box consists of four diodes connected in a bridge circuit used to convert alternating current (AC) input into direct current (DC) output. The unit features a clear circuit diagram as well, so students see the importance of diodes and how to rectify alternating current to direct current. Size: 13 x 8 x 5cm.
This activity set allows students to conduct activities to illustrate electromagnetism, induction and basic transformer experiments. This kit consists of a plastic base, a laminated iron core, mounting fixtures, and six coils protected in a heat resistant film. Topics covered include Lenz' Law, Faraday's Law, how iron cores increase magnetic field strength, and electromagnetic induction itself. This versatile piece of equipment can also be used to teach about how transformers used by power companies carry electrical energy.
This kit contains all the material required to build six complete motor models. Includes 12 magnets, six armatures, six pieces of mild steel yokes, six support bases, six support shafts, 24 connecting rivets, 12 split pins, one reel of 25 s.w.g., PVC tinned copper wire, two reels of cellotape, 300mm rubber tubing, and instructions.
