Key Features
Insulated copper wire coil wound on a magnetic core
Connection terminals for a low-voltage DC supply
Attracts iron filings, pins, nails and other magnetic materials while current flows
Magnetism weakens or disappears when the current is switched off
About This Product
The electromagnet shows that magnetism produced by a current is temporary and can be switched on and off. Students compare its pull as the current, the number of turns or the distance to the object is changed, and relate it to electric bells, relays, motors and lifting magnets. It should not be left switched on for long periods. Educational Instrument can dispatch the Electromagnet to laboratories in Saint Vincent and the Grenadines, Ghana, Armenia, Philippines and Angola.
Frequently Asked Questions
Does the Electromagnet stay magnetised after switching off?
No. The magnetic effect reduces or disappears when the current is switched off, which shows the temporary magnetism of an electromagnet.
