With the arrival of the rare earth magnetic material neodymium (NdFeB) in 1986 many products underwent significant changes, particularly in the electrical and electronics industry. The advantage of neodymium magnets is the relative ease with which they can be processed. Whereas ferrite magnets usually have to be shaped in a mould, neodymium magnets can be sawn or milled to shape. Furthermore, due to their high magnetic force they can be made smaller than the weaker ferrite magnets, which means that products such as electric motors can be made considerably lighter.

The list of applications for permanent neodymium magnets is long and varied: refrigerators, audio/video equipment, microwave ovens, dishwashers, metal separators, switches, clamping systems, starter motors for cars, hard disk systems for computers, and even sensors, pumps and fans.

Products

Magnetic inspection rods

Magnetic inspection rods enable you to determine whether your product is contaminated with ferromagnetic (Fe) particles. The inspection rods attract very fine Fe particles as small as 30 microns.

Gauss meter / teslameter

The gaussmeter/teslameter measures the local flux density, of a surface for example. The measurements can be displayed in units of tesla, gauss, kA/m or oersted.

More information

Magnetic polarity indicators

The Goudsmit Magnetic Systems pole indicator is used to determine the direction of a magnetic field. The indicator measures whether a magnetic pole is a magnetic north or south pole.

Magnetic viewing film

This flux-detector film makes magnetic fields visible.

More information

Plate demagnetizers

Plate demagnetizers are used for the removal of magnetism from flat metal products or those that are magnetized on one side only.

More information

Demagnetizing tunnels with rectangular passage

Intended for long, thin-walled products and materials with an irregular surface. Can be used in combination with conveyor belt or roller conveyor for products packed in boxes or on pallets.

More information

Demagnetizing tunnels with round passage

Suitable for installation in a pipe system and for the demagnetization of round objects. Also for links in push belts or balls in ball bearings.

More information

Low-frequency demagnetizing tunnels

Low-frequency demagnetization tunnels have high penetration power and are therefore suitable for thick-walled or solid objects; also for hardened steel or packaged products.

Demagnetization - Service on location

We also remove undesired magnetism as a service. You can send us your product, or our specialist can come to you to solve your problem.

More information

Demagnetization bars

For the demagnetization of tools and machine parts in difficult-to-reach places. For example, in workshops, tool-making shops, machine building and for watch repairs.

More information

Portable demagnetizers with round passage

For the demagnetization of tools and small materials. For example, drill bits and chisels, tools and small parts.

Ultrasonic welding of magnets

Ultrasonic welding is a means to encapsulate magnets or provide a casing. It is a welding technique in which objects are joined using high-frequency ultrasonic acoustic vibrations.

More information

Gluing magnets

Goudsmit regularly uses adhesives for product assembly. We know exactly how much to use and the best curing process, both of which are essential to ensure the product functions correctly.

More information

Overmoulding of magnets

Magnets are overmoulded when they must be completely covered for environmental reasons. This is an excellent technique for securely assembling parts.

More information

Injection moulding of magnets

Injection moulding is usually used to join magnets and plastics without gluing. This is a technically advanced solution that requires precision moulds and magnets. Goudsmit has what it takes.

More information

Assembling magnets mechanically

Press fits and screws are some non-risky methods for assembling magnetic systems. Mechanical assembly is sometimes preferable, because it is easy to test and inspect.

More information

AlNiCo pot magnets

AlNiCo pot magnets have a very high application temperature. The housing is steel, with a non-magnetizable material in between.

More information

Ferrite pot magnets

Ferrite or ceramic pot magnets are fitted with a steel pot that provides shielding from the magnetic field. The minimal installation height offers many constructive advantages.

More information

Electromagnets

Round electromagnets are switchable. They serve for picking up, positioning or holding products.

Permagraph

Using the permagraph we determine the exact magnetic properties and compare them to the required specifications.

More information

3D flux meter

Ideally, the border runs exactly between the north and south poles and perpendicular to the north-south axis. With the 3D fluxmeter we measure the actual angular deviation.

More information

Mobile demagnetization unit

The compact, mobile demagnetization unit is flexible and easy to move. Ideal for hard-to-reach places or when you don't need to demagnetize daily.
