See Electromagnetic Principles Come to Life in the Classroom
The Model 24014 Electromagnetic Relay Teaching Instrument transforms abstract circuit-control theory into a hands-on, fully visible demonstration. Designed for science teachers, lab instructors, and curious learners alike, this compact apparatus lets students watch every stage of electromagnetic relay operation — coil energization, core magnetization, armature attraction, and circuit switching — in real time, right on their desk.
Made in Mainland China.
What's in the Box
- Electromagnetic relay demonstration unit (Model 24014)
- Blue coil assembly mounted on metal support brackets
- Pivoting metal armature lever with spring return mechanism
- Connecting wires and electrical terminal posts (orange & black fittings)
- Sturdy black rectangular base for stable tabletop use
Key Features
- Fully Visible Components: Every part — coil, armature, contacts, and terminals — is openly mounted so students can follow the entire switching sequence without obstruction.
- Compact & Portable: Measures approximately 15.5 × 10.5 × 7.5 cm and weighs just ~237 g. Light enough for teachers to carry between classrooms and for students to pass around for closer inspection.
- Complete Circuit Control Model: Supports experiments involving electromagnetic coil control, armature switching, and relay-driven circuit activation — core topics in secondary and tertiary physics curricula.
- Durable Construction: Metal brackets, spring mechanism, and secure terminal posts are built to withstand repeated classroom use and student handling.
- Versatile Learning Settings: Equally effective for formal physics lessons, structured lab experiments, science fair demonstrations, and independent at-home study.
Educational Benefits
By allowing learners to physically manipulate connections and observe the relay responding in real time, the 24014 bridges the gap between textbook theory and practical understanding. Students retain concepts more effectively when they can see and interact with the mechanism — making this an invaluable addition to any physics lab or STEM classroom.

Frequently Asked Questions
Q: What age group or education level is the Model 24014 Electromagnetic Relay Teaching Instrument suitable for?
A: The 24014 electromagnetic relay physics teaching instrument is designed primarily for middle school, high school, and introductory college-level physics students. Its clearly visible components and straightforward operation make it accessible for younger learners while still offering enough depth for advanced science demonstrations.
Q: Does this electromagnetic relay demonstration kit come with instructions or experiment guides?
A: The kit includes the fully assembled relay apparatus with connecting wires and terminal posts. For best results, teachers are encouraged to pair it with their standard physics curriculum materials on electromagnetic induction and circuit switching to design guided experiments.
Q: Can students use this relay teaching instrument independently, or is it only for teacher-led demonstrations?
A: Both! The compact, portable format means teachers can use it as a front-of-class demonstration tool, and its lightweight, durable construction also allows individual students or small groups to handle and experiment with it independently — making it perfect for lab stations, science fairs, and at-home exploration.
Q: What power source is needed to operate the 24014 relay demonstration apparatus?
A: The 24014 is designed to be connected to a standard low-voltage DC power supply typically used in school physics labs. Please refer to your school's lab equipment guidelines for the appropriate supply voltage for safe operation.
