25 years of commercial PFMs at Hirst Magnetic Instruments

The first commercially available Pulsed Field Magnetometer (PFM) from Hirst was announced in 1998 (with the first machine shipped in 1999) but research work had been started 10 years earlier as it was clear modern high coercivity magnets could not always be measured on the traditional permeameters due to pole piece saturation and faster testsContinue reading “25 years of commercial PFMs at Hirst Magnetic Instruments”

Launch of GM09-1 Gaussmeter

Hirst Magnetic Instruments Ltd, is pleased to announce the launch of a new Gaussmeters the GM09-1. The GM09-1 features a touch-screen interface and rechargeable Li-ion battery compatible with the extensive range of Hirst Hall sensor probes. Built-in “App” modes ensure standard tests and measurements can be carried out with ease and minimal effort. The GM09-1 isContinue reading “Launch of GM09-1 Gaussmeter”

Hirst demonstration for HRH Prince Edward, The Duke of Edinburgh at the IOP

Hirst Magnetic Instruments joined a cohort of current and former Institute of Physics  business award winners being brought to Royal attention at the Physics Powering the Green Economy reception. This event was held at the Institute of Physics on February 8th and Dr James McKenzie was honoured to introduce Hirst’s PFM technology to HRH Prince Edward,Continue reading “Hirst demonstration for HRH Prince Edward, The Duke of Edinburgh at the IOP”

Hirst featured in IOP “Physics Powering the Green Economy”report

Hirst Magnetic Instruments was featured as a case study in the recent Institute of Physics (IOP) Physics powering the green economy report. There were 19 case studies in the report which was presented by the IOP at COP 28 in 2023. Hirst produces equipment to enable the decarbonisation of transport via electric motors which byContinue reading “Hirst featured in IOP “Physics Powering the Green Economy”report”

Developing next generation PFMs through the KTN Innovation Exchange (iX)

Hirst Magnetic Instruments Ltd seeks to use open innovation – via the Innovate UK iX approach (KTN-iX™) to understand the unexplored dynamic nature of eddy current and hysteresis losses in permanent magnets in motors and generators. Hirst Magnetics carry out magnetic measurements using a pulsed field magnetometer. The development of more powerful motors in theContinue reading “Developing next generation PFMs through the KTN Innovation Exchange (iX)”
