Colossal magnetoresistance effect B-scalar magnetic field sensors with effective areas of 0.05 mm^2 were used very close to the rails for magnetic field measurements. These measurements were performed during static and dynamic railgun experiments. In static experiments three different rail materials were used and the results are compared to a finite element simulation.
The design, technology and main characteristics of Ag contacts as well as "loop effect" peculiarities of colossal magnetoresistance B-scalar high magnetic field sensor based on La_{1-x}(Ca)Sr_x MnO_3 films used for measuring high magnetic field pulses are presented.
