20.500.12556/DKUM-92313 Contactless determination of a permanent magnet’s stable position within ferrofluid The paper deals with the contactless detection of a rod permanent magnet’s position within a ferrofluid. The working principle of the proposed approach is grounded on the solenoidal nature of the field lines. For the line detection technique analyzed in this article, where the magnetic field is scanned along the line parallel to the magnet’s axial direction, the center of the magnet corresponds to the point on the line where the radial component of the magnetic field vanished. The concept introduced here was evaluated numerically, where the results showed a promising perspective for the technique to be employed in practice. In contrast to the X-ray or Vernier-caliper-based technique, the one proposed here is somewhat more suitable for employment in applications where simplicity and robustness are of vital importance. permanent magnet levitation ferrofluid magnetic sensor magnetic field finite element method FEM permanentni magneti levitacija magnetni senzorji magnetne tekočine metoda končnih elementov true false true MDPI AG Angleški jezik Slovenski jezik https://www.mdpi.com/journal/mathematics © 2022 by the authors Članek v reviji 2025-03-28 12:34:12 2025-03-28 12:34:13 2025-03-29 03:12:48 0000-00-00 00:00:00 2022 0 0 12 str. no. 14 Vol. 10 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2022-05-31 2022-07-16 2022-07-18 537 118958595 10.3390/math10142499 2227-7390 mathematics-10-02499-v2.pdf mathematics-10-02499-v2.pdf 1 594E9807CE8AC2A5ECC9B63135D7F8AC 2005144a3619ff41f61b95413fe32c02da322309b55e6ec1fb5d2ebf0605457e cc9b6ffa-0bc8-11f0-af5a-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189785 https://www.mdpi.com/2227-7390/10/14/2499 0 d198dfb9-0bc8-11f0-af5a-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189786 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
