Contactless Wiegand Effect DC and AC current sensor
Štefánek, Martin ; Szabó, Zoltán (referee) ; Kubásek, Radek (advisor)
The paper describes the types of magnetic sensors, which are used for measuring magnetic fields. The document is divided into chapters, which describe Wiegandův sensor and its implementation into the magnetic sensor in this document is designed magnetic circuit design for this sensor. The work evaluates the progress in the design of contactless ammeter that measures AC and DC current via Wiegand effect. Experimental verification principle and its function for DC current is described in the penultimate chapter.

Measurement of magnetic quantities - estimation of the uncertainty
Šlichta, Pavol ; Šedivá, Soňa (referee) ; Havlíková, Marie (advisor)
This Master’s thesis contains an overview of determining measurement uncertainties of direct and indirect measurements. It describes a way of creating a magnetic field with the help of Helmholtz coil and a more detailed description of some principles of magnetic field sensors. This thesis also contains a description of the experiments and the factors influencing them. The last part deals with the quantification of uncertainties from measured experiments and with the discussion of the results from these measurements.
