Product Code : SCL-EE-12387
Quick Answer: The Electromagnet ‘U’ shape has a U-shaped soft iron core with series-connected enamelled copper windings, used to show how current magnetises an iron core and attracts an armature.
Last updated: October 2026
Key Features
- U-shaped soft iron core, 100 mm x 65 mm, formed from 16 mm diameter bar
- Core ends ground for good magnetic contact with the armature
- 0.9 mm enamelled copper windings on insulation bobbins, connected in series
- 4 mm sockets for laboratory leads
- Recommended current 5 A, maximum 8 A
- About 75 N needed to pull the armature away at 1 A

About This Product
Connected through its 4 mm sockets to a suitable supply, the windings magnetise the soft iron core so that it holds the armature, and the pull needed to separate them shows the strength of the effect. The magnetism lasts only while current flows, and the apparatus is used for teaching temporary magnetism, magnetic circuits and electromagnetic force. Besides buyers across India, the Electromagnet ‘U’ shape can be exported to institutions in Mauritania, Honduras, United Arab Emirates, Portugal and Mozambique.
Frequently Asked Questions
Q1. How strong is the electromagnet?
About 75 N is needed to pull the armature away from the core when 1 A flows through the windings.
