Induced Current Apparatus
Product Code : SCL-PLE-11682
The StemAids Induced Current Apparatus (often referred to as a Primary and Secondary Coil Set) is a precision-engineered electromagnetics demonstrator designed for the empirical study of mutual induction. Optimized for Secondary and University-level physics, this apparatus facilitates the quantification of magnetic flux linkage between two electrically isolated circuits. Manufactured to ISO 9001:2015 standards, it provides a high-stability platform for verifying Faraday’s Law and Lenz’s Law within institutional laboratory environments.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Nested Solenoid Architecture: Facilitates student visualization of magnetic field expansion and contraction across independent circuits, supporting Electromagnetism Module 201.
- Mutual Induction Interface: Enables the physical study of electromagnetic coupling, allowing learners to apply the principle of transformer action without physical contact.
- Lenz’s Law Verification: Supports the analysis of current directionality relative to the motion of the primary coil or the insertion of the iron core.
- Flux Density Evaluation: Allows students to evaluate the impact of core material (air vs. iron) and the rate of change of current on the magnitude of the induced electromotive force (EMF).
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) with specialized internal stabilization to prevent winding deformation or terminal damage.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and illustrated Experiment Guides in English.
- Durability: Tropicalized design featuring high-temperature resistant wire insulation and moisture-stable coil formers for reliable performance in varied climates.
Direct OEM Sourcing Advantages
Procuring the StemAids Induced Current Apparatus directly ensures vertical manufacturing control:
- In-House Precision Winding: Coils are batch-tested for uniform DC resistance and turn-density to ensure predictable experimental results.
- Batch-Tested for Uniform Reliability: Every unit undergoes an insulation breakdown test to ensure safety during high-frequency AC demonstrations.
- Direct Factory Spares Availability: Guaranteed availability of replacement primary/secondary coils and standardized soft iron cores to maximize long-term laboratory ROI.
- Manufacturing Control: Direct oversight of copper purity and mandrel concentricity ensures zero parasitic induction interference across all production lots.
