Oersted Rectangular Coil Setup

Product Code : SCL-EI-10662

The Oersted Rectangular Coil Setup from Lab Glassware Manufacturer is a physics laboratory electromagnetism apparatus used to demonstrate that an electric current produces a magnetic field around a conductor or coil.

Quick answer: The Oersted Rectangular Coil Setup recreates Hans Christian Oersted’s classic experiment, letting students see a nearby magnetic needle or compass deflect when current flows through a rectangular coil, demonstrating the link between electricity and magnetism. The exact coil turns, current rating, and wire material vary by model — check the specific listing before ordering.

Technical Specifications

• Rectangular coil format for a clear, structured classroom layout.
• Electromagnetism teaching aid for lessons on current, magnetic field direction, and the link between electricity and magnetism.
• Classroom demonstration value so students can observe magnetic needle movement during current flow.
• Low-voltage practical use for safe educational circuits where voltage and current ratings are confirmed.
• Specification-dependent safety — current limit, insulation, terminals, and coil heating behaviour are confirmed at order stage.

What Is Included

Oersted Rectangular Coil Setup with rectangular coil, base, and terminals. A magnetic needle or compass, connecting leads, activity sheet, storage box, or certificate may be included depending on the configuration ordered — confirm exact contents with Lab Glassware Manufacturer before ordering.

Applications / Uses

• Demonstrating the magnetic effect of electric current
• Showing magnetic needle deflection near a current-carrying coil
• Explaining the relationship between electricity and magnetism
• Studying current direction and magnetic field direction
• Supporting school and college physics practicals on electromagnetism
• Using in STEM demonstrations, science exhibitions, and electronics trainer lessons

How to Use the Oersted Rectangular Coil Setup

1. Place the setup on a stable, dry, non-magnetic laboratory bench.
2. Confirm the voltage rating, current rating, terminal layout, and coil limit before use.
3. Position the magnetic needle or compass near the rectangular coil if supplied or required.
4. Connect the coil to a suitable low-voltage power supply through a switch.
5. Switch on the circuit briefly and observe the needle deflection.
6. Reverse the current direction and compare the change in deflection.
7. Record observations and relate them to the magnetic field produced by current.
8. Switch off the supply before changing connections or handling the coil.

Safety note: Use only with safe low-voltage supplies unless the apparatus is specifically rated otherwise. Do not exceed the confirmed current rating, because coils may heat during operation. Keep magnetic needles away from strong magnets and sensitive electronics.

Care & Maintenance

• Store the setup dry and protected from dust, impact, and corrosion.
• Keep terminals clean and tighten loose connections before classroom use.
• Do not bend the coil, overload the circuit, or operate the coil continuously beyond its rating.
• Remove from use if insulation cracks, terminals loosen, or the coil overheats.

Part of a Complete Electromagnetism Teaching Sequence

The Oersted Rectangular Coil Setup pairs naturally with other magnetism apparatus from Lab Glassware Manufacturer. Combine it with the Small Compasses (4 pcs.) or the Transparent Compass Ø 45 mm to observe needle deflection, and the Magnetic 3D Field Demonstrator to extend the lesson into visualising the shape of the magnetic field itself.

Frequently Asked Questions

What is the Oersted Rectangular Coil Setup used for?
The Oersted Rectangular Coil Setup is used to demonstrate that electric current produces a magnetic field that can deflect a nearby magnetic needle or compass.

Why is a rectangular coil used?
A rectangular coil gives a clear classroom layout for showing the direction and effect of a magnetic field around a current-carrying conductor.

Does the setup include a compass or magnetic needle?
Compass or magnetic needle inclusion varies by unit — check from the final supplied kit configuration before ordering.

What current rating is required?
The current rating varies by unit — check the safe current or voltage limit from the product label, datasheet, or supplier before ordering.

Can students reverse the current direction?
Yes, current reversal can be demonstrated if the circuit is wired safely and the power supply and switch arrangement support it.

Is it suitable for school physics labs?
Yes. It is suitable for supervised school and college physics practicals on electromagnetism.
