Numerički pristupi u određivanju raspodele magnetnog polja i sile levitacije kod stalnih magneta
Numerical methods for permanent magnet's magnetic field distribution and levitation force calculation : doctoral dissertation
sr
Permanent magnets are increasingly being used as a result of the wider adoption of electrical devices and gadgets. There is a constant need for their optimization and size reduction, leading to new mathematical methods for their field calculation. The quality of electrical devices that contain permanent magnets is dependent on the magnetic material they are made of, their magnetization, and their size. Many different methods for permanent magnet field calculation are available, aiming towards the simplest and fastest analysis of magnetic structures in relation to different parameters. In most cases, analytical methods for permanent magnet field calculation based on the distribution of magnetic charges or Ampere's microscopic currents are limited to block and cylindrical structures. In order to overcome drawbacks of analytical and numerical methods, this theisis presents two additional, semi-numerical approaches.
