Compass Manufacturer,Supplier and Exporter in India

Compass (Product Code: SCL1379/026) is a compact student compass: a 40 mm magnetic needle on a conical bearing, enclosed in a cylindrical transparent plastic box 45 mm across. The needle is held on its median axis so that it does not drop off when the box is turned or tilted, which makes it practical to hand out to every pair of students. Its N and S ends are coloured blue and red. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, and suits bulk supply for school physics lab equipment in India.

Specifications

Typical Use

The most common classroom task is plotting field lines: students place a bar magnet on paper, set the compass near one pole, mark where the needle points, move the compass to that mark and repeat, joining the dots into a field line. The transparent case lets them see the paper beneath, and because the needle is retained on its axis the compass can be picked up and repositioned again and again without the needle falling off.

It is equally useful for finding north before setting up experiments that need a fixed orientation, for showing that a current-carrying wire deflects a nearby needle, and for simple outdoor direction-finding activities. Remind students that the blue end marks N on this model, keep the compasses away from magnets when they are stored together, and wipe the plastic case clean with a dry cloth.

Manufacturer

The compass comes from Jain Scientific Equipments Private Limited, an Ambala, Haryana manufacturer that markets its classroom and laboratory products as ScienceLab. Learn about the company on the ScienceLab profile.

Related Lab Equipment

Magnetism practicals that use this compass usually need these items too:

• Bar Magnet (Plastic) — the magnet whose field students plot.
• Magnetic Compass Needle — a larger needle for the teacher’s front-of-class demonstration.
• Compass Plotting (Clear) — an alternative plotting compass for larger groups.
• Device for Demonstrating Magnetic Field Lines — shows the whole field pattern at once for comparison with plotted results.

More student apparatus is available in the Lab Equipment category.

Frequently Asked Questions

How big is the compass?
The needle is 40 mm long and sits in a transparent plastic box with a 45 mm diameter, small enough for field-line plotting on an exercise-book page.

Will the needle fall out if a student turns the compass over?
No. The needle pivots on its axis in a way that keeps it from falling when the box is twisted, which suits handling by students.

Which colour marks north?
On this compass the N pole is blue and the S pole is red, so it is worth pointing this out before a plotting exercise.

Why does the needle sometimes point the wrong way?
A compass stored touching a strong magnet can have its needle remagnetised in reverse. Store compasses apart from magnets and check them against a known north before class.

Can I order a full class set?
Yes. Tell us how many compasses you need and where they should be delivered; we quote for schools across India and buyers in international markets.

Is there a warranty?
Warranty terms are given with each quotation. Please ask through the contact page if you need them before placing an order.
