Ferrite Discs
Product Code : EL-M-10305
Quick answer: Ferrite discs are ceramic disc magnets with high coercivity, so they resist demagnetisation, and their low cost suits class sets. They come in six diameter x thickness sizes from 15 x 3 mm to 35 x 8 mm and are used for attraction, repulsion, stacking and field-mapping activities. Lab Exports manufactures them in Delhi for schools, colleges and universities.

How ferrite discs are used
Ferrite magnets are made from iron oxide combined with barium or strontium carbonate, pressed and sintered like a ceramic. Their high coercivity means an external field or a knock does little to weaken them, and their low cost makes it practical to give every group its own set. The trade-off is brittleness: the discs can chip or crack if dropped or allowed to snap together.
Students use them to compare the strength of different sizes by the number of paper clips each lifts, to find which faces attract and which repel, to stack discs and see how the pull increases, to map the field of a flat magnet with a plotting compass, and to build simple compasses and motors in STEM projects.
Key features

- Low cost makes bulk sets for every student group practical.
- Six diameter and thickness combinations, 15 to 35 mm across.
- Flat disc form suits stacking, sticking and field-mapping activities.
- Ceramic material does not rust.

Frequently asked questions
What sizes of ferrite disc are available?
Six diameter x thickness sizes: 15 x 3, 18 x 5, 20 x 3, 30 x 5, 32 x 4 and 35 x 8 mm.
How should ferrite disc magnets be handled?
Ferrite is hard but brittle, so avoid dropping the discs or letting them snap together, and slide them apart rather than prising them.
