Introduction

Hirst Magnetic Instruments Ltd. design and manufactures magnetising systems capable of magnetising permanent magnets and assemblies containing permanent magnets.

Hirst’s range of easy to operate magnetising systems offers flexibility and control at both high and low production rates. They can be operated as stand-alone systems, integrated with other Hirst Magnetic Instruments Ltd. products or integrated with customer’s external equipment.

Models are available in each range suitable for magnetising any suitable material including:

NdFeB - Neodymium Iron Boron
Sm2Co17 -Samarium Cobalt 2-17
SmCo5 - Samarium Cobalt 1-5
Strontium Ferrite
Barium Ferrite
Alnico/Alcomax
All other permanent magnet materials

Hirst Magnetic Instruments Ltd. has developed a series of magnetisers that support a variety of applications, a selection of which is indicated below:

Saturation of permanent magnet and magnet assemblies
Magnetising sub assemblies containing the magnet which avoids contamination
Laboratory work where magnet development is undertaken
Multi-pole magnetising of rare earth magnets
Manufacture of permanent magnet motors or voice coil motors
Servicing areas such as motor repairs

Next >The Magnetising Process

TURNKEY SOLUTIONS

Our approach objective is simple, total customer satisfaction. From initial consultation, through the design phase to manufacture and supply, Hirst will effectively manage the whole process making your "turnkey solution" a reality.

MAGNETISER PRODUCT RANGE
	MCSD Series Magnetiser The MCSD series specifically uses non-polar capacitor technology
	MCD Series Magnetiser The MCD series is similar to the MC series but has the ability to demagnetise
	MC Series Magnetiser The MC series is capable of handling medium to high production rates
	M Series Magnetiser Magnetisers from this range are best suited for low to medium production rates

CHOOSING THE RIGHT SOLUTION

To help us provide the best solution for your magnetising application, we have prepared a short on-line questionnaire. Please view this questionnaire to enable us to provide a quick response to your requirements.

MAGNET CHARACTERISATION

	INTRODUCTION
	OPEN + CLOSE MAGNETIC CIRCUIT
	EDDY CURRENTS
	COMPARISON OF TECHNOLOGY USED IN MEASURING MAGNET CHARACTERISTICS

Introduction

The purpose of a magnetic characterising system is to determine the magnetic properties of a magnet or magnetic material. This information can be used for testing batches of all magnets in production, quality issues and research purposes.

The principles behind the technologies can be described as:-
“By applying a known magnetic field to a magnetic specimen, the applied field strength is monitoring against the specimen’s own magnetism (total flux) with the resultant changes being recorded for analysis”.

The magnetic characteristic is obtained by analysing the applied magnetic field and the sample’s own magnetism.

Although the principles are simple, it is the method of generating the applied field and measuring the magnets “magnetism” that differentiate between the various methods of measurement available, along with the limits to data available and the range each system can operate over.

Magnet characterising technologies include:

Before describing the above technologies in more depth, consideration needs to be given to two important factors in choosing a magnetic characterising technology namely,Open and Closed Magnetic Circuit EffectandEddy Currents.

The comparision table highlights at a glance the features of each technology used in the measurement of magnet sample characteristics

MAGNET CHARACTERISATION TECHNOLOGIES

Pulsed Field Magnetometry (PFM)

Pulsed Field Magnetometers apply a “pulse” of magnetic field to generate the applied magnetic field. This has the advantage that the field can be strong enough to saturate any magnetic material.

Vibrating Sample Magnetometry (VSM)

Vibrating Sample Magnetometers vibrate the sample as part of the measurement process. This provides the Fluxmeter element of the system with the dynamic component it requires to make the measurement. The applied field is changed so at each measurement point the field is static and hence no eddy currents to cause problems.

Permeameter Technology

Permeameters use a closed loop form of magnetic measurement.

Introduction

Hirst Magnetic Instruments Ltd. design and manufacture demagnetising systems capable of reducing the existing flux in magnets, ferrous material, magnet housings and equipment.

Hirst’s range of easy to use demagnetising systems offers flexibility and control at both high and low production rates. They can be supplied for manual operation, with suitable PLC interface controls or integrated with other Hirst products.

Models are available in each range suitable for demagnetising permanent magnets or ferrous material.

Demagnetising materials, (or degaussing or deperming as it is also known), plays a vital role in the flow of work of many industrial processes around the world.

Components may become magnetised as part of the production process or are supplied magnetised (intentionally or otherwise). They often need to be demagnetised to avoid production problems, to make handling easier or to recycle components.

It is therefore necessary to remove, or greatly reduce this unwanted magnetism.

TURNKEY SOLUTIONS

DEMAGNETISER PRODUCT RANGE
	MCSD Series Demagnetiser The ideal general purpose machine where the ability to magnetise and demagnetise from a single unit is required
	MD Series Demagnetiser The MD range of demagnetisers is fully microprocessor controlled
	AC Demagnetiser Suitable for small, low field demagnetisation
	PDM Precision Demagnetiser Are used to achieve very accurate demagnetisation.

CHOOSING THE RIGHT SOLUTION

To help us provide the best solution for your demagnetising application, we have prepared a short on-line questionnaire. Please view this questionnaire to enable us to provide a quick response to your requirements.

INSTRUMENTS

The two main magnetic field properties of magnets which are normally measured are magnetic flux density and magnetic flux (Click here for an explination between magnetic flux density and magnetic flux).

Measuring each of these characteristics requires the use of a different type of magnetic instrument:

To measure flux density – use a Gaussmeter (or Teslameter)

GAUSSMETERS

	PRODUCT RANGE
	CALIBRATION STANDARD
	HALL EFFECT PRINCIPLE
	GAUSSMETER SELECTION FACTORS
	HALL PROBES

To measure total flux – use an Integrating Fluxmeter

	INTRODUCTION
	DETAILED INFORMATION

GAUSSMETERS Gaussmeters measure magnetic flux density. The vast majority of Gaussmeters use the Hall effect principle to measure magnetic flux density. More info…	FLUXMETERS Integrating Fluxmeters are used to measure magnetic flux, and unlike Gaussmeters need a changing magnetic environment to support measurement. More info…
