Measures approximately 4.75" x 4" x 1.75" (12 x 10 x 4.5cm) Magnet comes as two coils wrapped on a U-shaped metal frame with attached armature Connect to a power supply at 4-6V and start magnetizing Great tool for teaching electromagnetics in the classroom Can be used to pick up metal objects, filter magnetics, and build pendulums When electric current runs through both coils of copper wire, it produces a magnetic field. Test the load limit of this U-shaped magnet using the attached armature. Perfect for physics demonstrations teaching students about electricity and magnetism.
Comprised of a 9mm diameter soft iron U, two copper wire coils measuring 0.7mm in diameter (270 turns). Two, 4mm sockets to connect to 4-6 volts D.C. power source. Use magnet with a DC power supply such as ELabs' 1A Regulated AC/DC Power Supply (PH1323A). Operational voltage is between 4 and 6 volts.
