Apparatus Force of Conductor
Apparatus Force of Conductor (Product Code: SLE/PHY/11) is a rolling-axle demonstration unit used to show Fleming's left-hand rule, the force on a current-carrying conductor in a magnetic field, in school physics labs. A brass axle with plastic discs rests on a pair of brass rails between the poles of a strong U-shaped magnet, and it rolls one way or the other depending on the direction of the current. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Force of Conductor Apparatus Used For?
This is the classic "motor effect" demonstration. Current enters one brass rail through a 4 mm socket, crosses the brass axle and leaves by the other rail, so the axle itself becomes the conductor sitting in the field of the U-shaped magnet. As soon as current flows, the axle is pushed along the rails; reverse the supply leads, or turn the magnet over, and it rolls back the other way. Students can predict each result with Fleming's left-hand rule before switching on.
Use a low-voltage DC source and switch the current on only briefly, as a short circuit through the rails and axle warms the leads quickly. The plastic discs keep the axle rolling true on the rails, so the effect is easy to see from the back of the room. As an electromagnetic kit for school physics, it links neatly to lessons on electric motors and on current-carrying coils.
OEM Manufacturer
Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the original equipment manufacturer (OEM) of the Apparatus Force of Conductor. The unit is built at the company's licensed factory at Saha, Ambala, Haryana, India, and goes out factory-direct to schools, teacher-training colleges, dealers and importers. If you later need a replacement axle, rails or magnet, or want to repeat an earlier order, ask the manufacturer directly. Read more on the company profile page.
Related Physics Lab Equipment
To run the demonstration and extend it into a full electromagnetism lesson, labs usually add:
- Power Supply, Stepped — a bench supply for sending current through the rails.
- Stackable Leads — leads for joining the supply to the socket terminals.
- Knife Switch – Single Pole — lets the teacher apply current in short bursts.
- Force on a Conductor Apparatus — an alternative design for the same Fleming's rule experiment.
- Induced Current Apparatus — shows the reverse effect, where motion in a field produces current.

Frequently Asked Questions
What does the Apparatus Force of Conductor demonstrate?
The Apparatus Force of Conductor demonstrates that a conductor carrying current in a magnetic field is pushed by a force. The brass axle rolls along the brass rails in one direction, and reverses when the current direction is reversed, which students can check with Fleming's left-hand rule.
What parts make up the force of conductor apparatus?
The force of conductor apparatus comprises a strong U-shaped magnet, a pair of brass rails fitted with 4 mm socket terminals, and a brass axle with plastic discs that is free to roll along the rails. A DC supply and connecting leads are needed to run it.
What power source does the Apparatus Force of Conductor need?
The Apparatus Force of Conductor is run from a low-voltage DC source connected to the 4 mm sockets on the brass rails. Switch the current on only for short periods. For advice on a supply that suits your lab, send your existing equipment list through the ScienceLab contact page.
Who manufactures the Apparatus Force of Conductor?
Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, manufactures the Apparatus Force of Conductor as the OEM at its own factory in Saha, Ambala, Haryana, India. Schools and dealers buy it direct from the manufacturer and can ask the same team for replacement parts.
Which class levels use the force of conductor apparatus?
The Apparatus Force of Conductor suits secondary-school lessons on the motor effect and Fleming's left-hand rule, and it is also used for revision demonstrations in senior-secondary and junior college physics. Teachers use it before introducing the electric motor so students first see the basic force on a single conductor.
How can I get a quotation for SLE/PHY/11?
