What is included in the General Items category?

Twenty-five physics apparatus and consumable items that don't sit under a single dedicated subcategory: precision measuring and weighing instruments, electrical wires and resistance coils, magnetism apparatus, calorimetry and heat-transfer equipment, renewable-energy demonstration models, and pendulum-bob sets, all listed on stemaids.com on 28 August 2026.

Is STEMAids a registered manufacturer of these items?

Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for the full registration and certification details -- manufacturer-stated, verify before citing in procurement documents.

Is a horseshoe magnet strong enough for electromagnetic induction demonstrations?

The Horseshoe Magnet (Rs 130) is specified for standard school-level magnetic field and induction demonstrations. For sonometer-linked electromagnetic experiments, the dedicated Electromagnet for Sonometer (Rs 155) is the better-matched apparatus.

What renewable-energy demonstration models are available?

Four models covering the CBSE Class X Sources of Energy chapter: an Electric Generator Demonstration Model (Rs 360), a Small Wind Energy Model (Rs 290), a Water Power Turbine Model (Rs 1,040), and a Windmill Activity Kit (Rs 440), useful for both classroom demonstration and STEM activity sessions.

Do you supply calorimeters for specific heat capacity experiments?

Yes. The Copper Calorimetry Instrument is listed at Rs 225 on stemaids.com and is specified for standard specific-heat-capacity practicals at the secondary and senior-secondary level.

Which wire should I order for a resistivity-of-a-wire experiment?

Constantan wire (Rs 110 per 100gm) and nichrome wire (Rs 150 per 100gm) are the two alloys most CBSE and state-board resistivity practicals specify, because their resistance is largely temperature-independent. Copper DCC wire (Rs 130) and brass wire (Rs 155) are typically used as comparison or connecting-wire samples rather than the primary resistivity specimen.
