Product Code : SCL-AM-12108
Electromagnet ‘U’ shape Two Coils (SKU SCL-AM-12108) is a U-shaped soft iron core carrying two copper coils, with a removable iron armature that the poles grip when current flows. It shows how an electric current creates a temporary magnet and how much load that magnet can hold, in secondary-school and college physics labs. Science Lab Supplies builds the electromagnet in its Saha, Ambala factory (Plot 448, HSIIDC Industrial Area) and supplies schools, colleges and distributors without a middleman.
Specifications
All technical details are listed in the table below. In summary, a horseshoe-shaped core of high-permeability soft iron carries two pre-wound insulated copper coils, connected through 4 mm safety binding posts and fixed on a non-conductive base, for use on 4–6 V DC at no more than 2 A.

Applications and Experiments for the U-Shaped Electromagnet
With the armature across both poles and the coils energised, the magnet holds the keeper and any load hung from its hook; switching off releases it because soft iron keeps little magnetism. This makes the unit a clear piece of electricity and magnetism lab kit for schools and college benches.
- Class 10 science: magnetic effect of electric current, powered from a Laboratory Battery Eliminator set between 4 V and 6 V.
- Lifting tests: hanging Laboratory Slotted Masses, 2.5 kg from the hook to compare holding force at different currents, read on an Ammeter.
- Class 12 physics: comparing an electromagnet with a permanent horseshoe magnet.
- Showing the link between current, number of turns and field strength.
Stay within 2 A so the coils do not overheat, remove the weights before switching off, and keep the pole faces clean and dry.
Standard Scope of Supply
The set comprises the U-shaped soft iron core assembly with its two pre-wound coils on the base, one soft iron armature with an integrated suspension hook, and an experiment guide with wiring schematics. The DC power supply, connecting leads and slotted weights are not included and can be quoted separately.

Frequently Asked Questions
What power supply does the Electromagnet ‘U’ shape Two Coils need?
It is designed for a low-voltage DC supply of 4 to 6 V, with the current kept at or below 2 A. Connect the supply to the 4 mm binding posts with standard banana-plug leads.
Why is the core U-shaped instead of straight?
Bending the core brings the north and south poles side by side, so a flat armature can bridge both at once. This closes the magnetic path and gives a much stronger pull on the keeper than a straight core would.
Does the core stay magnetised after switching off?
Very little. The core is soft iron, which loses almost all of its magnetism as soon as the current stops, so the armature and any load are released when the supply is turned off.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures this electromagnet itself. Production takes place at the company factory in Saha, Ambala, India, and the quotation you receive is issued directly by the maker with no trading firm involved.
