Set of Coils with Removable Iron Core
Product Code : SCL-CL-11875
Set of Coils with Removable Iron Core (SKU SCL-CL-11875) contains three copper-wound coils of 300, 600 and 1200 turns for teaching electromagnetism: magnetic fields of currents, electromagnetic induction and the effect of a core on field strength. It suits Class 10–12 practicals and first-year college labs. Science Lab Supplies arranges supply of the set from Ambala, India to schools, colleges, training institutes, distributors and tender contractors.
Specifications
Turn counts, winding and terminals of the three-coil set are each given a row below. In short, every coil is wound on a hollow tube, so with the core removed it acts as an air-core coil with relative permeability close to 1, while square endplates hold the copper windings and insulated screw-type binding posts take the leads.

Applications and Experiments for the Set of Coils
With three turn counts and a core that can be taken out, students can change one variable at a time and see how turns, current and core affect a magnetic field or an induced voltage. The set covers magnetic effects of current in NCERT Class 10 and electromagnetic induction in Class 12 physics.
- Class 10 science: field of a current-carrying coil traced with a 2 cm Compass.
- Class 12 physics: Faraday's law, moving a magnet into a coil and comparing 300, 600 and 1200 turns.
- Electromagnet strength with and without the iron core, wired to the binding posts with Cables with Plug.
- B.Sc. and diploma labs: mutual induction between two coils of different turns.
Standard Scope of Supply
The set comprises the three coils of 300, 600 and 1200 turns and the removable iron core named in the title. A power supply, galvanometer or meter, magnets and connecting leads are separate items, and each of them can be itemised on the same quotation if requested.
Packing, MOQ and Lead Time
You can price one set for the teacher's bench or several for group practicals. The quotation shows packing, delivery time and price for that number, and as a laboratory equipment supplier in India, Science Lab Supplies can include a power supply and leads alongside the coils.
Science Lab Supplies can ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria under its Importer-Exporter Code. For coil-set pricing, describe your practical on the contact page or collect the items in the enquiry cart; institutions buying through tenders can consult the lab tender page.
Frequently Asked Questions
How many turns do the coils have?
The set has three coils with 300, 600 and 1200 turns, so the number of turns can be doubled and doubled again within a single experiment.
Why is the iron core removable?
With the core out, each coil behaves as an air-core coil whose field stays proportional to current. Inserting the core shows how iron strengthens the field of an electromagnet.
Who supplies the Set of Coils with Removable Iron Core?
This coil set is quoted by Science Lab Supplies and sent from Ambala, India. Schools, colleges, training institutes, distributors and tender contractors can request one set or several.
What else is needed for induction experiments?
A magnet, a sensitive meter such as a galvanometer and connecting leads, plus a DC supply for electromagnet work. Send your experiment list and the matching items can be quoted with the coils.
