   3.High-uniformity Electromagnets (highest uniformity up to 10ppm/cm3 )
    
SB-type electromagnets are Coliy's new-generation dual-tone double yoke structure electromagnets. SB-type electromagnets, whose two-way adjustable magnetic field gap and double-
yoke structure forming a closed magnetic circuit, have a better rigidity and the horizontal magnetic field; inclined yoke 45 degree angle, to facilitate handling of samples and with other devices combined into architecture. 
 The design and magnetic circuit of SB-type electromagnets are reasonable. Pole sizes from 100mm-250mm and weight from 200KG-1920KG, form a series of products. Electromagnet fine processing ensures the pole coaxial collimated and ampere turns in the line package of the most number, which can be concentrated to a minimum volume, to make the excitation power per kilowatt to get the strongest magnetic field per unit volume inside the line package. Meanwhile, it can be working air gap in the immediate vicinity of the greater patency. Electromagnet can be naturally cooled and can also be water cooled , to ensure that the electromagnets work under normal temperatures. SB-type electromagnet gap adjustment range is wide, and the pole is easy to replace, suitable for a variety of magnetic measurements.

User can configure a number of different sizes of pole in an electromagnet and independently replace the pole.

Uniformity of the magnetic field is determined by the following factors: the electromagnet power, pole diameter, gap. The magnetic field uniformity can be  up to 10ppm per cm3 by selecting the appropriate parameters.
