DESIGN AND MANUFACTURING OF A MAGNETIC SWITCH BY USING OIL-BASED FERROFLUID AND OIL-BASED FERROFLUID DOPED WITH COPPER NANOPARTICLES

In this work, design and manufacturing of the magnetic switch was prepared from the pure oil-based ferrofluid and froma Ferro fluid doped with 0.012mg copper nanoparticles. The properties and applications of ferrofluid were studied, and the effect of laser light on these samples were studied.The main parameters of the magnetic switch by using oil-based pure ferrofluid were studied such as rise time ,fall time and response time where, ( Rise Time = 6.451 ms.)( Fall Time = 75ms) (Response time =12.09ms). The same parameters for the magnetic switch by using oil-based ferrofluid doped with copper nanoparticles were studied, where, the (Rise Time=4.261 ms.)(Fall time= 58.52ms) and (Response Time=7.95ms ). also in this work ,a magnetic hysterical loop in different forms, according to the type of material used in making the magnetic switch sample, and the properties of these materials were identified by this study.
