Electromagnet
Product Code : SCL-M-11183
Quick answer: This electromagnet has insulated copper coils on a U-shaped soft iron core, so both poles face the same way for strong lifting. Run from 4-6 V DC through 4 mm terminals, it holds a soft iron armature with a hook and releases it when switched off, showing how current creates a magnetic field. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the electromagnet experiment is done
A current in a coil produces a magnetic field, and a soft iron core inside the coil strengthens that field many times because the iron is easily magnetised. Soft iron also loses almost all of its magnetism when the current stops, which is what makes an electromagnet switchable. Bending the core into a U brings both poles to the same side, so the armature closes the magnetic circuit and is held far more firmly than by one pole alone.
- Place the electromagnet on a stable bench and connect the 4 mm terminals to a variable DC supply, with an ammeter and rheostat in series if current is to be measured.
- Set the supply to 0 V, switch on and raise the voltage slowly, staying within the recommended 4-6 V.
- Offer the armature to the poles and hang masses from its hook to find the load it can hold.
- Repeat at different currents and note how the holding force changes; switch off and observe the armature drop.
Key features
- Soft iron core magnetises quickly when energised and releases the armature when switched off.
- U-shaped core brings both poles together for strong lifting demonstrations.
- Insulated copper windings on protected bobbins resist wear from classroom handling.
- Standard 4 mm binding posts connect to laboratory power supplies, meters and rheostats.
- Hooked armature takes slotted masses for holding-force tests.

Frequently asked questions
What voltage does the electromagnet need?
A DC supply of 4-6 V is recommended, connected through the 4 mm terminals; start at 0 V and increase slowly.
Why is the electromagnet core made of soft iron?
Soft iron is magnetised strongly by the coil current and loses nearly all its magnetism when the current is switched off, so the magnet can be turned on and off.
