Ring ferrite magnets – did they really produce the sound of our childhood?

Yes! The famous big and heavy speakers that the lucky ones of us had at home, where real rock music was played, incorporated ring ferrite magnets. Ring ferrite magnets are also known as toroidal ferrite magnets.

And today, although miniaturization is being sought, there are still producers who use ring ferrite magnets for a high-fidelity sound. But neodymium ring magnets are also used more and more often.

Do I have to disassemble a speaker for a ring ferrite magnet?

Not. We at supermagneti.ro offer you a wide range of such ring ferrite magnets (toroidal) with different sizes and strengths! We have in our range both tiny ring magnets, with a diameter of 8 mm with an attractive force of 130 grams – HFE-R-8-4-3, but also giants such as the toroidal ferrite magnet with a diameter of 100 mm and a force of 16 kg – HFE-R-100-60-20.

Should I buy a ferrite or neodymium magnet?

This is influenced by how you want to use the magnets. Here are some purchase suggestions:

We especially recommend buying ferita magnets in the following situations:
– Small budget per project
– Use in high temperature conditions (80-250 degrees Celsius)
– Indoor or outdoor use
– Aesthetics less important.

We especially recommend neodymium magnets in the following situations:
– High attraction or repulsion force is required
– Space is limited (miniaturization)
– The final object or project must be lighter
– The finish must be beautiful.

The cost of ferrite, as a material, is much lower than neodymium (Neodymium Iron Boron). On the other hand, a neodymium magnet has an adhesive force that is approximately 4-5 times greater than that of a ferrite magnet. If you calculate the cost per kg of adhesive force, ferrite magnets are approximately 2 to 3 times cheaper than neodymium magnets. This is especially true for block or ring magnets and for larger quantities, with magnets in small quantities things can be different.

Strong ferrite magnets are very large, which makes them dangerous even for children (see safety tips).

[icon name=”magnet” class=”” unprefixed_class=””] All ferrite ring magnets have poles on flat circular surfaces (axial magnetization).

There are many options of toroidal ferrite magnets. I haven’t listed them all, if you are interested in a specific model of ring ferrite magnet, especially in large quantities, we can discuss the needs of the project and make an attractive offer.
