Electromagnet “U” Shape
Product Code : SCL-M-11228
Quick answer: The U-shape electromagnet is a coil-and-core apparatus whose U-shaped core brings two poles close together. When current flows through the winding the core is magnetised and attracts iron objects; switching off largely removes the effect. It is used to show the magnetic effect of current and to compare electromagnets with permanent magnets. Lab Exports manufactures it in Delhi for schools, colleges and universities.
Specifications

Core material, winding, operating voltage, current rating and lifting capacity are confirmed with the quotation; a power supply, switch and leads are not included unless quoted.
How it is used in teaching
Oersted's discovery that a current produces a magnetic field is the basis of every electromagnet. Winding the wire into a coil adds together the fields of all the turns, and a magnetic core inside the coil concentrates the flux. With the core bent into a U, both poles face the same way, so they grip an iron bar together and the effect of switching the current on and off is easy to see.
- Place the apparatus on a dry bench and check the winding, terminals and leads for damage.
- Confirm the permitted voltage and current from the quotation or label, then connect a suitable DC supply through a switch.
- Switch on and test which objects are attracted; use a plotting compass to identify the two poles.
- Switch off and watch the objects released, then compare with a permanent horseshoe magnet.
Key features
- Shows directly that an electric current produces a magnetic field.
- U-shaped core places both poles together for clear attraction tests.
- Switchable action lets students compare on and off states.
- Poles can be found with a plotting compass and reversed by reversing the current.
- Links current-and-field theory to relays, lifting magnets and electric bells.

Frequently asked questions
How is an electromagnet different from a permanent magnet?
An electromagnet is magnetic only while current flows in its coil, and its strength and polarity change with the current; a permanent magnet keeps its field all the time.
What power supply does the U-shape electromagnet need?
The operating voltage and current are not listed on this page; email [email protected] with house code SCL-M-11228 so the quotation confirms the rating and a matching supply.
