Ampere's Rule Apparatus Manufacturer,Supplier and Exporter in India

Ampere's Rule Apparatus (Product Code: SLE/EM/08) is a physics apparatus used to observe the magnetic field around a current-carrying wire in Grades 9–12 classrooms. Supplied with a manual, one 45-mm compass and six 16-mm compasses, it lets students apply the right-hand rule and see how the field varies with distance and with the plane studied. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Ampere's Rule Apparatus Used For?

Start with the 45-mm compass beside the wire and the current off, so the needle settles on north. Switch the supply on and the needle turns; reverse the leads and the swing reverses, so the class can predict each direction with the right-hand rule before switching. The six 16-mm compasses are then arranged around the wire in the perpendicular plane to trace the circular field, and moved outwards step by step to show the deflection falling off with distance.

Repeating the layout in the plane parallel to the wire shows how field direction relates to the current along its length. Switch the current on only while readings are being taken, keep magnets and steel items away from the bench, and line the wire up north–south for the clearest deflections. The apparatus works as a front-of-class demonstration and as a magnetism experiment kit for pairs of students at their own benches.

What to Specify When Ordering

• The number of Ampere's Rule Apparatus sets: one for teacher demonstration, or one per student pair for practical work.
• Whether a regulated DC power supply should be quoted, since none is included.
• Whether banana/alligator cords should be quoted with each set, as they are also not included.
• Any extra plotting compasses you want for mapping larger field patterns.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Ampere's Rule Apparatus and makes it at its own licensed factory at Saha, Ambala, Haryana, India. Purchase departments that register vendors can use the company's GSTIN 06AAECJ8618A1ZT and Legal Entity Identifier 3358004HRD1JIVXKYX49.

Schools, dealers and importers buy the apparatus factory-direct, and replacement compasses or repeat orders can be requested from the manufacturer itself; ask us. The company profile gives further background.

Frequently Asked Questions

What comes with the Ampere's Rule Apparatus?
The Ampere's Rule Apparatus is supplied with a manual, one 45-mm compass and six 16-mm compasses, which together let students detect the field beside the wire and map its pattern around the conductor.

What else is needed to use the Ampere's Rule Apparatus?
The Ampere's Rule Apparatus requires a regulated DC power supply and banana/alligator cords, neither of which is included. Both can be quoted on the same order as the apparatus if your laboratory does not already have them.

What current setting should be used?
A recommended current is not stated in our current product details for the Ampere's Rule Apparatus. The supplied manual covers operation; for guidance before purchase, please contact us and the manufacturer will answer directly.

Which classes is the Ampere's Rule Apparatus designed for?
The Ampere's Rule Apparatus is designed for Grades 9–12, covering the magnetic effect of current, the right-hand rule and how magnetic fields change with distance from a current-carrying wire.

How much bench space does the Ampere's Rule Apparatus take?
The Ampere's Rule Apparatus measures 17.5 x 7.5 x 10 cm, so it fits easily on a student bench next to the power supply, leaving room to arrange the compasses around the wire.

Who manufactures the Ampere's Rule Apparatus?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, is the OEM manufacturer of the Ampere's Rule Apparatus, producing it at its own licensed factory at Saha, Ambala, Haryana, India, and supplying schools and dealers factory-direct.

Is a calibration certificate available for the Ampere's Rule Apparatus?
The Ampere's Rule Apparatus is a demonstration apparatus rather than a measuring instrument. If your institution needs documentation, including a calibration certificate, discuss it with us through the contact page when requesting a quotation for India or international delivery.
