Magnetic fields for medical experiments
Punčochář, Marek ; Cipín, Radoslav (referee) ; Patočka, Miroslav (advisor)
his work deals with the creation of magnetic fields for medical experiments. The first part deals with different types of coils, with a focus on the Helmholtz coil. Longer be described here how the winding coil-shaped mats, calculate the length of the field lines. After the work is focused on the involvement of the coil into the circuit.

Magnetic fields for biomedical experiments
Otýpka, Jan ; Cipín, Radoslav (referee) ; Patočka, Miroslav (advisor)
In this work deals with magnetic fields for use in biomedicine. This solution involves the choice of the correct geometric arrangement of coils for generating magnetic field with a homogeneous distribution of magnetic induction of the widest possible area. The paper compares thre traditional types of coils, solenoid, toroid and Helmholtz coil. For Helmholtz and solenoid coil and is then carried out an analysis of the magnetic flux density in the inner space. Next part is devoted to electrical resonance in the LC circuit. This is then utilized for the development of pulsed magnetic field in the Helmholtz coil. It summarizes the theoretical and practical knowledge to design and construction of resonant converters. The end is devoted to the measurement of circuit parameters and verification of theoretical knowledge.

Draft controlled modular source 6,3kA / 5VAC for warming trials and tests breakers
Zolich, Ladislav ; Dostál, Lukáš (referee) ; Dohnal, Petr (advisor)
The main object of this thesis is to design a toroidical transfomer on the given parameters. Project is focused on learning about principles of transformers, it’s designing and mainly on designing the given transformer. Designing contains material selection of the core of the transformer, its size, then calculating magnetic flux, no-load current, cross-section of conductor and calculating no-load losses and joule losses. The next part is designing the mechanical parts of transformer, its terminal plate, base and cooling system. Thesis is also mainly focused on designing the form for potting the transformer in epoxy resins. In the end is measurement and form of powering the transformer.
