MIRABAL GARCIA, M. et al. Diseño y construcción de un magnetizador de pulsos. Rev. mex. fis. [online]. 2005, vol.51, n.5, pp.542-548. ISSN 0035-001X.

In the present paper we present the design and construction of a pulsed field magnetizer that has been set up at the IF-UASLP. The system is based on the discharge of the energy stored in a capacitor bank (C_total = 23.1 mF; U = 1/2CV² ≈2300 J ) into a resistive double-layer copper solenoid supported by reinforcing glass fibers. This magnetizer is capable of generating pulsed magnetic field strengths up to 9.0 T, in a cylindrical volume of 17 mm diameter at the center of the solenoid, with a pulse duration of about 2.0 ms. The principle of operation of the magnetizer as well as the design of the field solenoid are described. A pick-up coil system combined with an electronic integrator is also available in the apparatus to monitor the shape of the field pulse, peak field, and pulse duration.
