Electromagnetism

Basic electromagnet construction, induction, and field visualisation each need different apparatus. Check your syllabus topic before ordering, whether that's a nail-and-wire kit or a C-core coil set.

A single battery suits basic electromagnet demonstrations, while induction and transformer experiments may need a variable power supply. Confirm your apparatus's voltage requirements before ordering.

Enamelled copper wire sold by the reel lets you rebuild coils repeatedly across lessons, while pre-wound cores and keepers offer a more durable, ready-to-use option for frequent demonstrations.

A single demonstration set suits teacher-led lessons, but hands-on electromagnetism practicals need enough wire, cores and batteries for every group to build their own electromagnet.

A basic electromagnet kit typically includes an iron nail, a reel of insulated copper wire, a battery, and paper clips to demonstrate the electromagnet's lifting power once built.

Adding more turns of wire, using a higher current, or using a larger iron core all increase an electromagnet's strength. Our C-core and keeper apparatus let learners test these variables directly.

A permanent magnet holds its magnetism constantly, while an electromagnet only becomes magnetic when electric current flows through its coil. Switching off the current switches off the magnetism.

The keeper bar bridges the two poles of the electromagnet, helping to maintain and demonstrate the magnetic circuit, and is commonly used to show the electromagnet's holding force.
