Measurement and recording of the initial magnetization curve and hysteresis curve of ferromagnetic materials
Tran, Quoc Bao ; Vaněk, Jiří (referee) ; Klvač, Ondřej (advisor)
This thesis deals with the measurement of primary magnetization curves and hysteresis loop. The thesis is divided into two parts, the theoretical part and the practical part. The theoretical part describes the creation of magnetic field in materials, excitation of magnetic field by electric current or excitation of electric current by changing magnetic field. The practical part is focused on designing, construction and testing of amplifier and the measurement and displaying of hysteresis loop. In the end of the thesis is summarized what results were achieved.

Device for magnetic mixing of solution containing magnetizable particles
Zítka, Jan ; Martiš, Jan (referee) ; Červinka, Dalibor (advisor)
The aim of this works was the design and construction of a device that will be used for magnetizable beads mixing without application of mechanical force. In theoretical part of this work, properties of ferromagnetic nano- and microbeads and methods used for mixing of these beads were described. Two coils were reeled in for the device, each consisting of 200 turns and with 0.8 . The device construction was designed in program CAD. Different parts of the instrument were 3D printed. The control program, which enables changes in coil switching, was created and then the testing of device functionality was performed.
