Hirst Magnetic Instruments Ltd can design and manufacture
custom magnetising and demagnetising coils, or fixtures as they are
generally known, to suit any particular application. Many of our
fixtures are manufactured as part of a magnetising or demagnetising
system.
We can design and build standard solenoid fixtures as well as
complex multipole, radial, skewed, Halbach and other special
configuration fixtures.
Custom fixtures may also contain embedded search coils to be
connected to a Hirst Integrating Fluxmeter as part of a quality control
or magnet calibration system.
Helmholtz Coils are a special type of fixture consisting of 2
parallel coils. The volume between the coils provides a very
uniform
magnetic field.
Hirst Magnetic Instruments also supply a range of
Electromagnets for the production of static or slowly changing magnetic
fields. These are driven by DC or AC electrical supplies which can also
be supplied by Hirst.
