Plotting Compass, Single Glass Face Manufacturer,Supplier and Exporter in India

Plotting Compass, Single Glass Face (Product Code: SLE/PHY/267) is a small magnetic compass in an aluminium case, used to trace magnetic field lines around magnets and current-carrying wires in school physics practicals. Teachers order it in packs of 10 for group work; each compass is 16mm in diameter, glass-faced on one side, with a dial marked with the cardinal and ordinal points. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, and suits any magnetism experiment kit.

Specifications

What Is a Plotting Compass Used For?

To map a field, place a bar magnet on a sheet of paper and set the compass near one pole. Mark a dot at each end of the needle, move the compass so its tail sits on the front dot, and repeat; joining the dots traces one field line, and starting from several points builds up the whole pattern. The same method locates neutral points between two magnets and shows the circular field around a straight current-carrying wire or the field of a coil. Because each compass is only 16mm across, plotted points sit close together and the lines come out smooth.

Before use, check that every needle settles in the same direction when the compasses are laid well away from magnets. Store the compasses in their pack, away from strong magnets that could weaken or reverse a needle, and handle them by the aluminium case to protect the glass face. Pair them with a bar magnet for school practicals, and with a current-carrying frame or coil for electromagnetism lessons.

What to Specify When Ordering

Frequently Asked Questions

What size is the Plotting Compass, Single Glass Face?
The Plotting Compass, Single Glass Face is 16mm in diameter, housed in an aluminium case. The small size lets students plot points close together around a magnet, so the field lines they draw are smooth and detailed.

How many compasses are in a pack of the Plotting Compass, Single Glass Face?
The Plotting Compass, Single Glass Face is supplied as a pack of 10. One pack can be shared across several student groups, or each group can have its own pack so several field lines are plotted at the same time.

How do students plot field lines with the Plotting Compass, Single Glass Face?
With the Plotting Compass, Single Glass Face, students mark the needle’s two ends as dots, move the compass forward so its tail sits on the front dot, and repeat. Joining the dots gives one field line around the magnet.

What does “single glass face” mean on this plotting compass?
On the Plotting Compass, Single Glass Face, only one side is glass-faced; the rest is an aluminium case. Students view the needle and the dial of cardinal and ordinal points through the glass from above as they plot.

How should the Plotting Compass, Single Glass Face be stored?
Store the Plotting Compass, Single Glass Face in its pack, well away from strong magnets that could weaken or reverse the needle. Hold each compass by its aluminium case to keep fingerprints and knocks off the glass face.

Who manufactures the Plotting Compass, Single Glass Face?
The Plotting Compass, Single Glass Face is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India, and supplied in packs to buyers in India and international markets.
