By performing magnet calculations we quickly determine which magnet is suitable for your product.

We put this question to magnet expert Marc Teeuwen. He explains, ‘Companies come to us with a problem concerning the integration of a magnet in a new or existing product. These magnets work together with sensors that guarantee flawless operation of countless devices.Consider, for example, the control unit for navigation and phone in cars or the control knobs for ovens and microwaves. And magnets are used at the high-tech level too, such as in linear drives for position determination at high speed.’

Magnet calculations
Marc says, ‘Exactly which magnet is suitable for a product and what the final power of that magnet will be, is difficult to determine. Goudsmit has experts on staff who can perform magnet calculations. When you have to do this yourself, it takes a lot of time before you finally find the suitable magnet. You search for a supplier, first request a sample, then test, adjust, reject and search again. Before you know it you are many months further along. Particularly when developing a new product you simply don’t have this time. In the meantime your competitor will have caught up with you or
production will have been at a standstill for months. This is every manufacturer’s nightmare.’

Knowledge is power
Marc continues, ‘Once we have a clear definition of the customer’s problem and all the data are known, our people can get started, on the basis of a predetermined step-by-step plan. That is the power of detailed magnet calculations. We determine which magnet allows your sensor/drive/product to function as desired. Ultimately this must also be tested in practice, but by then you are already at 95% sure you have the right solution. That costs much less time and therefore money.

Moreover, we can also simulate and theoretically underpin the solution, thanks in part to the magnet measurements. And the quality controls we carry out also offer the assurance that you are buying a properly functioning product. Our commitment to quality demonstrated by the fact that we are
a ISO/TS 16949 and AS9100c certified company.’

’To ensure the magnet functions over a certain distance, just knowing the flux density is not enough. The exact magnet value depends on numerous factors. Such as how it is mounted – horizontally or vertically – and the thickness of the steel present. And whether there are any magnetic materials
nearby that may dampen a portion of the magnetic field. But also the distance – is it fixed or does it vary within a few milimetres?

With our magnet calculations we offer the assurance that you have the right magnet for the right application!’
