Electromagnetic Induction Tester – Coil & Circuit Fault Detector
Electromagnetic Induction Tester – Coil & Circuit Fault Detector
Electromagnetic Induction Tester – Fast Coil & Circuit Board Fault Detection
This compact Electromagnetic Induction Tester is designed for electricians, automotive technicians, and electronics enthusiasts who need a quick, accurate way to check inductors, coils, and motherboard components. Simply plug in via the Type-C interface, press the button, hover the sensing tip over the component — and an LED indicator tells you instantly whether the inductor is functioning normally or has a fault. No guesswork, no complex setup.
Made in Mainland China.
Key Features
- High-Sensitivity Detection: Accurately identifies working or faulty inductors and coils on circuit boards, motherboards, and automotive electronics — even on densely packed PCBs.
- Instant LED Feedback: Light on = inductor working normally. Light off = inductor malfunction detected. Diagnose issues in seconds.
- Type-C Powered: Powered via a standard Type-C cable (not included) — no battery needed, no replacements, no downtime.
- Ultra-Portable & Lightweight: Weighing just 4 g and measuring 7.5 × 2.7 cm (approx. 2.95 × 1.06 in), it fits easily in any toolbox, kit bag, or pocket for on-site use.
- Wide Application: Ideal for computer motherboard diagnostics, car electronics troubleshooting, bench testing, and general electrical maintenance at home or in the workshop.
- Durable Build: CE-certified electronic components deliver stable, long-lasting performance for professionals who need tools they can rely on daily.

Frequently Asked Questions
Q: What does this electromagnetic induction tester actually detect?
A: This inductance tester uses electromagnetic induction to check whether coils and inductors on circuit boards, motherboards, and automotive electronics are functioning properly. When the LED lights up, the component is working normally; when the LED stays off, a fault has been detected in the inductor or coil being tested.
Q: Does the electromagnetic induction tester require batteries?
A: No batteries are required. The tester is powered via a standard Type-C USB cable. Simply connect it to any USB power source (phone charger, power bank, laptop port, etc.) before use. The Type-C cable is not included.
Q: Is this tester suitable for automotive use as well as computer motherboards?
A: Yes — the tester is designed for both automotive electronics (e.g. car ECU coils, ignition-related components) and computer/electronics motherboard diagnostics. Its compact, portable design makes it easy to take to a car workshop or use at an electronics repair bench.
Q: How close does the sensing tip need to be to the component?
A: For best results, bring the sensing tip as close as possible to the inductor or coil — ideally touching or just grazing the component surface. The high-sensitivity design allows detection on densely packed PCBs without needing to desolder components first.
