Applications

Permanent magnets are everywhere from aerospace to automotive they are in the vast majority of electric motors. They are used in a huge range of sensors to offshore wind generators and every loudspeaker and every microphone in every phone.

Hirst has been providing industry leading solutions for over 60 years.

Hirst is the leading provider of pulse field magnetometers (PFMs) used by magnet manufacturers to develop and characterise the high performing magnets underpinning these applications.

Magnetic characterisation – PFMs

The PFM-07 range (PFM12 and PFM14) of magnet characterisation / magnetometer can accurately measure the magnetic hysteresis curve and extract key values for all magnetic materials (Ferrite, NdFeB, SmCo, AlNiCo). With a maximum of 10.5T (8356 kA/m / 105 kOe) even the most coercive materials and highest grades of NdFeB can be measured while traditional permeameters cannot measure these high coercivity materials due to pole piece saturation limitations. The 7th generation of PFMs from Hirst uniquely feature eddy current correction (patented F-2F algorithm) and Self Demagnetisation Field (SDF) correction. The first generation of Hirst industrial PFM was launched in 1998 and this latest generation was launched in 2021 with new high-performance 2.4GHz wireless sample holders.

Demagnetisers

Hirst Magnetics has been producing demagnetisers since the 1960’s and its bench-top demagnetisers, workstation demagnetisers and volume production demagnetising systems are trusted by the world’s leading companies in industries ranging from aerospace and electronics to medical equipment and automotive.

A common problem in industry is residual magnetism in parts after machining or working.  Often parts stick together, proving difficult for additional processing. Another typical problem after machining is that parts can pick up swarf, and even washing can prove ineffective. By demagnetising parts these problems can be alleviated.
