Electromagnetic levitation
Kondys, David ; Červinka, Dalibor (referee) ; Martiš, Jan (advisor)
The thesis deals with the issue of magnetic levitation. It is divided into two main chapters. The first chapter is focused on a general introduction to magnetic levitation. It describes the types of magnetic levitation, their use and the principle of execution. The end of the chapter is focused on a more detailed description of magnetically levitated MAGLEV trains. It describes the history of these trains, their use and construction. The second chapter is focused on the design of a device for demonstrating magnetic levitation. First, it deals with the simulation of an electromagnetic problem in the FEMM program. In addition, for the selected position configuration of the electromagnet and levitating magnet, it describes the design of the construction of the device in SOLIDWORKS and its manufacture. The result of the work is an attempt to make such a device that can stably keep the levitating magnet in the air.

Cell labeling with magnetic particles
Kukhta, Dziyana ; Janoušek, Oto (referee) ; Čmiel, Vratislav (advisor)
This bachelor thesis describes the movement of cells labelled with magnetic nanoparticles in the magnetic field in the direction of the magnet. First, it describes two types of magnets: permanent magnet and electromagnet. Then, it is dedicated to magnetic field sensors, magnetic nanoparticles and their incorporation in cells, optical systems for detecting cell movement and the effect of electromagnetic fields on cells. The practical part is dedicated to the incorporation of nanoparticles in cells, the measurement of the magnetic field intensity of a neodymium magnet and an electromagnet, and the methods of electromagnet control. It also describes the effect of electromagnetic fields on fibroblasts and the concentration of nanoparticles on the ability of the labelled cells to react to a magnetic field. The last part is dedicated to the production of a flow chamber, the analysis of the movement of cells in the chamber and the subsequent capture of cells in various magnetic fields.

Production of electricity from the vibration of the bicycle
Novák, Pavel ; Sobotka, Jiří (referee) ; Koutný, Martin (advisor)
The work is focused on methods of obtaining energy from the environment. In the project, there are summarized and generally described some methods of energy conversion. A more detailed description is aimed at a method on the principal of the Faraday's effect. The work involves a calculation of the electromagnetic generator with specific parameters, a simulation of the calculated generator and builds a real product on the basis of the previous theoretical calculation. The aim is to create a product that accumulates the energy obtained in the attached battery.

Apparatus for electromagnetic levitation
Kondys, David ; Vorel, Pavel (referee) ; Martiš, Jan (advisor)
This paper deals with magnetic levitation. It is divided into two main chapters. At the beginning of the first chapter, it discusses the types of magnetic levitation and describes their use in practice. It then focuses on the MAGLEV high-speed trains that use magnetic levitation. The second chapter is about the practical fabrication of equipment to demonstrate magnetic levitation. In the beginning, it discusses possible designs of magnetic levitation and evaluates this. Next, it simulates the chosen design and produces a graph from the simulations describing the force required to pick up a preselected object. It also discusses possible distance sensors that may be useful for this design. Finally, it describes the practical fabrication of the device design, i.e., the fabrication of the solenoid coil and the solenoid holder. Finally, it evaluates the measured values when the device is started.
