Product Code : SCL-M-11246
The U-Core Electromagnetic Assembly is an educational physics apparatus used to demonstrate how electric current produces a magnetic field in a wound coil and magnetic core. It enables school, college and technical laboratory students to investigate electromagnets, magnetic attraction and basic magnetic-circuit behaviour through supervised practical experiments.
Product Description
The assembly uses a U-shaped magnetic core configuration that provides two pole faces for electromagnetism demonstrations. When an appropriate low-voltage current passes through the winding coil or coils, the core becomes magnetized and can attract a compatible armature or magnetic specimen.
This apparatus supports practical teaching within physics laboratory equipment programmes. Its visible arrangement helps learners connect electric current, coil winding and magnetic attraction with the operation of relays, electric bells, lifting magnets and other electromagnetic devices.
Key Features
- U-core configuration: Provides two magnetic pole faces for clear classroom demonstrations.
- Hands-on electromagnetism: Shows that a current-carrying winding produces a magnetic field.
- Removable assembly format: Allows students to examine the relationship between the core, coils and armature, subject to the confirmed model configuration.
- Low-voltage laboratory use: Designed for connection to a suitable current-limited educational power source.
- Observable magnetic attraction: Allows learners to test the attraction of compatible ferromagnetic objects.
- Reusable teaching apparatus: Suitable for repeated supervised demonstrations when correctly operated and stored.
- Curriculum-supporting application: Useful for lessons covering magnetic effects of current and electromagnetic devices.

How to Use the U-Core Electromagnetic Assembly
- Inspect the core, coils, terminals and connecting leads for visible damage.
- Check the confirmed voltage and current rating before making any connection.
- Position the coil or coils correctly on the U-shaped core.
- Place the armature or test object close to the two pole faces without forcing it into position.
- Connect the apparatus to a switched-off, current-limited low-voltage power supply.
- Switch on the supply briefly and observe the magnetic attraction.
- Switch off the power before changing the armature, connections or coil arrangement.
- Repeat only within the confirmed operating limits and allow the coils to cool when necessary.
Safety note: Never connect the assembly directly to mains electricity. Prolonged energization or excessive current can overheat the winding. Use the apparatus only under qualified supervision.
Care & Maintenance
- Keep the core surfaces clean and dry to reduce corrosion.
- Do not pull, crush or scrape the coil windings and terminals.
- Store the core, coils and armature together in a dry cabinet.
- Disconnect the power immediately if the coil becomes unusually hot or emits an odour.

Frequently Asked Questions
What is a U-Core Electromagnetic Assembly used for?
It is used to demonstrate how electric current flowing through a coil creates a magnetic field and magnetizes a U-shaped core.
Why is the magnetic core U-shaped?
The U shape creates two adjacent pole faces. This arrangement allows an armature or magnetic object to bridge the poles and complete a shorter magnetic path.
Does the assembly include two coils?
The number of coils depends on the supplied model. Confirm the coil quantity, turns and electrical rating before publishing or ordering.
Can students vary the magnetic strength?
Magnetic attraction can be compared by changing the current only within the confirmed apparatus rating and under teacher supervision.
Is a power supply included?
A power supply is not included unless specifically stated in the commercial specification. Use a compatible current-limited low-voltage laboratory supply.
Can the apparatus be connected to mains electricity?
No. Direct mains connection is unsafe and can damage the winding. The assembly must be operated only at its confirmed low-voltage rating.
