Methods of single impulse detection
Juřík, Vladimír ; Bartušek, Karel (referee) ; Fiala, Pavel (advisor)
This thesis deals with measurement method pulsed quantities of electromagnetic field. This thesis was focused on methods, which make use of optic effect. Specially Faraday effect, Pockels effect and magneto-optic Kerr effect. Next it was focused on method makes use of Rogowski coil. At the end was shortly noticed about method makes use of calorimetric sensor. For experimentally realized has been chosen Faraday Magneto-optic Effect. In optic laboratory has been realized absolute methods and different methods making use of Wollaston polarizer on pneumatic optical desk. The main advantage of this method is the capability to measure the high frequency and high current signals. Next in this thesis has been written theory about Rogowski coil. This method has been experimentally realized in laboratory.

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.
