Compass 1
Compass 1 (Product Code: SCL265/033) is a 100 mm round magnetic compass used to find direction relative to the Earth's magnetic poles in school physics and geography lessons. Its large silver dial marked with the cardinal points and its well-balanced needle let a whole group read it at once, which suits teacher demonstrations. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as physics lab equipment for India and abroad.

What Is the 100 mm Magnetic Compass Used For?
In physics, a compass is the simplest detector of a magnetic field. Set Compass 1 on the bench, let the needle settle along the north–south line, then bring a magnet or a current-carrying wire close and watch the needle swing. Moving it step by step around a bar magnet lets students mark the field direction at each point and join the marks into field lines — a classic magnetism experiment for school labs in India. The 100 mm dial is easy to read from a short distance, so a teacher can show the effect to a small group first.
In geography and outdoor lessons it introduces bearings: hold the compass level, turn it until the North mark lines up with the needle, and read off the direction of a landmark. Take readings away from steel benches, stored magnets and electrical cables, and keep the compass flat in a drawer so the balanced needle is not jarred.
OEM Manufacturer
Compass 1 is produced by Jain Scientific Equipments Private Limited, which trades as ScienceLab, at its own licensed factory in Saha, Ambala, Haryana. As the OEM, the company makes and assembles the compass itself rather than buying it in from a trader, so schools, colleges, dealers and importers deal directly with the source. Repeat orders and replacement units are handled by the manufacturer as well — ask us about current availability. Read more on the ScienceLab company profile.

Frequently Asked Questions
What is the diameter of Compass 1?
Compass 1 has a 100 mm round body with a silver dial showing the cardinal points. The larger size makes the needle and markings easier to read at a glance, which helps during teacher demonstrations and group work in school labs.
What is the needle of Compass 1 mounted in?
The well-balanced needle of Compass 1 is mounted in an aluminium case with a glass top. The listing also names plastic and stainless steel among its materials, so ask us if you need the material of each part confirmed before ordering.
Can Compass 1 be used to trace magnetic field lines?
Yes. Compass 1 responds to any nearby magnetic field, so moving it around a bar magnet and noting the needle direction at each point reveals the field pattern. For fine plotting on paper, many teachers add small plotting compasses alongside it.
Who manufactures Compass 1?
Compass 1 is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Schools, dealers and importers buy it direct from the maker, and repeat orders are handled by the same company.
How should Compass 1 be stored and handled?
Store Compass 1 flat, away from magnets, steel shelving and electrical equipment, which can disturb the needle. Handle it gently so the balanced needle is not knocked, and wipe the glass top with a soft, dry cloth after use.
Is a calibration certificate available for Compass 1?
Compass 1 is a teaching compass for direction-finding and magnetism experiments. If your institution needs any calibration or test document with the order, please raise it through our contact page before ordering so we can tell you what can be provided.
What details are needed for a Compass 1 quotation?
For a Compass 1 quotation, tell us the quantity, the product code SCL265/033, your delivery location in India or abroad, and any other magnetism items you want on the same order. Bulk supply for schools, dealers and importers is quoted directly.
