Magnetic Field Demonstration Device
Product Code : SCL-PL-11833
Magnetic Field Demonstration Device (SKU SCL-PL-11833) is a two-part demonstration set that shows the magnetic field produced by current in a circular coil and in a straight conductor, with a compass, magnetic rod and iron filings for mapping the field. It supports Class 10 and Class 12 lessons on the magnetic effects of current. Made by Science Lab Supplies at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, it is manufactured for schools, colleges, tender contractors and distributors, who buy direct.
Specifications
The device combines a circular-coil field apparatus and a straight-conductor field apparatus, so both classic current-field patterns can be shown with one purchase. A 16 mm aluminium magnetic compass indicates field direction, while a 100 mm magnetic rod and iron filings give a permanent-magnet pattern for comparison.

Applications and Experiments for the Magnetic Field Demonstration Device
With current passed through the coil or the straight wire, iron filings and the compass reveal circular field lines around the conductor and the stronger, more uniform field at the centre of a loop. Students can then relate direction of current to direction of field using the right-hand rule.
- Class 10 science: magnetic field due to a current in a straight conductor and in a circular loop.
- Class 12 physics: moving charges and magnetism, field of a circular current loop.
- Comparing a current-produced field with that of the 100 mm magnetic rod.
Standard Scope of Supply
One device includes the circular-coil magnetic field apparatus, the straight-conductor magnetic field apparatus, a 16 mm diameter aluminium magnetic compass, a 100 mm magnetic rod and iron filings. A current source and connecting leads are not part of this set and can be added to the quotation.
Packing, MOQ and Lead Time
Ask for a price on a single device for teacher demonstrations or on several for group practicals. Each quotation shows how the order is packed, how long delivery takes and the price at that quantity, and it can include a power supply or other items from the range.
Science Lab Supplies has an Importer-Exporter Code and can ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. Enquiries are welcome through the contact page and the enquiry cart, and institutions buying by tender can refer to the lab tender page.
Frequently Asked Questions
Which fields can the Magnetic Field Demonstration Device show?
It shows the field around a straight current-carrying conductor and the field of a circular coil, plus the pattern of a permanent magnet using the 100 mm rod and iron filings.
Is a power supply included?
No current source is listed in the set. A suitable supply and leads can be added to the same quotation on request.
Is Science Lab Supplies the manufacturer or a trader?
The company manufactures the device. It is produced in Saha, Ambala, India, in the company's own factory, and buyers deal with the maker from enquiry to dispatch.
How does it differ from the Magnetic Field Lines apparatus?
That apparatus uses a 220 V coil, a 50 x 7 mm magnet and test nails and clips; this device adds a straight-conductor set and a compass for current-field work.
