Hirst Magnetic Instruments was presented with its 2020 IOP business innovation award at the IOP Celebration of Physics event 27.6.23 held at Aerospace Bristol.
The award was originally given to Hirst for its PFM work in 2020 but with recent events the IOP has decided to recognise the achievements of its 2020, 2021, and 2022 Award Winners in person at this celebration of physics event.
Hirst is part of the 2020 cohort of business award winners.
Hirst has now developed a significant advance of the PFM process with mathematical support from the University of Exeter. These new PFM self demagnetisation field function (SDFFTM) units allow closed-circuit magnetic measurements to be made in open-circuit circumstances, something which has not been possible before.
This is an essential step needed for the accurate characterisation of actual production magnets prior to assembly and magnetisation.
This was an industry first and solves a high-value industrial market challenge.
This technology extends the PFM open-loop process, allowing closed-loop measurements to be made by using a proprietary new field interpretation model operating on a proven technology platform.
