摘要：
A magnetic structure for use in vacuum gauges, which comprises a sheath of ferromagnetic material within which are held a first and a second magnetic array, each array:
having a plurality of magnet components to form the complete array
being magnetised such that the poles of the magnet components lie substantially on lines emanating radially from the magnetic structure main axis
having a polarity opposite to the other array
being longitudinally spaced apart from the other array.
