Plotting Compass
Product Code : LSK-PL-10305
Plotting Compass (SKU LSK-PL-10305) is a 16 mm compass in an aluminium case, glass faced on one side, for tracing the direction of magnetic field lines point by point around magnets and current-carrying conductors. It suits school and college magnetism practicals as well as simple direction-finding. Science Lab Supplies makes the compass at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and deals with schools, colleges, tender contractors and distributors without intermediaries.
Specifications
Size, case, face and dial of the plotting compass each take a row. In short, a 16 mm aluminium case with a glass face on one side shows the needle from above, and the dial carries the cardinal and ordinal points, so the same compass serves field plotting and simple direction-finding.

Applications and Experiments for the Plotting Compass
Placed on paper beside a magnet, the compass needle lines up with the local field. Students mark the ends of the needle, move the compass forward and repeat, building up field lines dot by dot, and the 16 mm size keeps each step short so the traced pattern shows fine detail.
- NCERT Class 6 science: magnets, poles and finding directions.
- Class 10 science: field lines of a bar magnet, checked against the pattern from a Pair of Bar Magnets with Iron Filings.
- Class 10–12: the field of a current loop on the Magnetic Field Demo, Round Coil, designed for mini plotting compasses.
- Class 12 physics and B.Sc. practicals: mapping fields and locating neutral points.
Keep the compass away from strong magnets when stored, as this can weaken or reverse the needle’s magnetism.
Standard Scope of Supply
Each Plotting Compass is supplied as a single unit: the 16 mm aluminium case with its glass face and marked dial. Magnets, drawing paper and the coil or wire for current-field work are separate, and compasses can be quoted in any number for class sets of school physics lab equipment in India.
Packing, MOQ and Lead Time
Compasses can be priced singly or by the dozen so every pair of students has one; each quotation sets out packing, delivery time and price for that quantity. Bar magnets and field demonstrators for the same practical can be added to it.
With an Importer-Exporter Code, Science Lab Supplies is a registered exporter that can ship to buyers in the Philippines, Nepal, Bangladesh, Zambia, Rwanda and South Africa. Ask for a class-set price via the contact page, put the compasses and magnets together in the enquiry cart, or tender through the lab tender page.
Frequently Asked Questions
What is a plotting compass used for?
It is used to plot magnetic field lines. Moving the small compass step by step around a magnet or a current-carrying conductor and marking the needle’s direction traces the shape of the field.
What size is the Plotting Compass?
It is 16 mm in diameter, in an aluminium case with a glass face on one side and a dial marked with the cardinal and ordinal points.
Is Science Lab Supplies the manufacturer or a trader?
These compasses are made at the Science Lab Supplies factory in Saha, Ambala, India; as their manufacturer, the company handles your quotation from that factory itself.
Can it be used as an ordinary compass?
Yes. Because the dial carries the cardinal and ordinal points, it can also show directions in simple orientation activities, though its main purpose is field plotting.
