This sturdy air-core copper solenoid is perfect for any classroom experiments requiring an external magnetic field. Insulated copper wire is wound around a plastic coil, and brass binding posts are attached to the end plates of the solenoid. Students can measure relationships between electricity and magnetism over a wide range of currents. Ensure the power supply used does not exceed 10A intermittently or 5A continuously.

Teacher Recommendation:

"I have found it indispensable for demonstrating magnetic forces produced by electric current and the fundamental principle of electro-magnetic induction. The dramatic effect of the magnetic field produced by the solenoid on a compass needle is easy to produce. Likewise, my students have gained a deeper understanding and appreciation for how electricity is generated. Using the coil, a bar magnet and a galvanometer the principle of electromagnetic induction is demonstrated for all to see."
