Coilgun
Kovařík, Martin ; Pavlík, Michal (referee) ; Šteffan, Pavel (advisor)
This bachelor’s thesis describes the design and construction of electromagnetic gun for testing projectiles from different ferromagnetic materials with maximal power 19 J. Conventional projectile propulsion mechanisms include the use of compressed air or explosion which places theoretical limits on the maximum muzzle velocity limited by laws of thermodynamics. The electromagnetic coil gun, explores the use of electromagnetism in accelerating projectiles which offers a much higher theoretical limit on muzzle velocity. In addition of an electromagnetic acceleration is possible to regulate output velocity/energy of projectile, and acceleration applied on projectile.

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.
