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. Use magnet with a DC power supply such as Eisco Labs' 1A Regulated AC/DC Power Supply (PH1323A). Operational voltage is between 4 and 6 volts.

• 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
