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. Physics teachers use it in Class 10–12 practicals and first-year college labs. The set is available from Science Lab Supplies in Ambala, India to schools, colleges, training institutes, distributors and tender contractors.
Specifications
Each 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, avoiding saturation and keeping the field proportional to current. Square endplates hold the copper windings on the bench, 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 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.
- 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 any optional accessories you ask for are itemised on the quotation.
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.
Science Lab Supplies can ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria under its Importer-Exporter Code. Enquiries are welcome through the contact page and the enquiry cart; institutional buyers can also 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 in 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?
Science Lab Supplies supplies the set from Ambala, India, quoting schools, colleges, training institutes, distributors and tender contractors directly.
What else is needed for induction experiments?
Typically a magnet, a sensitive meter such as a galvanometer and connecting leads, plus a DC supply for electromagnet work. Tell us your experiment list and we will quote the matching items.
Related Electromagnetism Items
Coil experiments need a current source, a magnet to move, a way to detect the field and good connections. These four items cover those needs for school and college electromagnetism practicals and can be quoted with the coils in one enquiry.
- Power Supply Unit/ Block for DC — drives current through the coils.
- Permanent Magnet Bar and Horseshoe — magnets for induction tests.
- Compass — traces the coil's magnetic field.
- Cables with Plug — leads to the binding posts.
