Summary: In this study, the trapped magnetic field is calculated numerically by varying the sample shape, dimensions and the distance between the sample surface and the observation point. The map of the trapped magnetic field is calculated using the sand-pile model and the Biot-Savart law. It is observed that this calculation method is useful for the determination of the magnetic characteristics of the sample. The trapped magnetic field is found to depend on the sample shape and dimensions and on the distance between the sample and the observation point. It is also observed that for the square sample the x- and y- components of trapped magnetic field are equal in magnitude, but opposite in direction. Another result is that the order of the samples in a cylindrical system affects the magnitude of the trapped magnetic field. In addition, it is found that a large single crystal cylindrical sample has a higher magnitude of the trapped magnetic field when compared to a system of samples with same size. It is also observed that in the system formed by identical cylindrical samples the trapped magnetic field decreases with the increasing sample number.Key Words: Superconductor, Trapped Magnetic Field, Sand-Pile Model, Biot-Savart Law, Maglev System
