surface induction
Permanent magnets influence their surroundings through their magnetic field that gradually weakens with an increasing distance from the magnet. Their shape and size are given by the magnet dimensions, shape, and material used. This is connected with homogeneity of the magnetic field around the magnet. The distribution of the magnetic field around the magnet and at its surface can be determined by measuring magnetic induction.
measurement of surface induction
Magnetic induction can be measured by means of spot measurements with teslameters with an axial or transversal Hall probe as well as by mapping using scanners over the magnet surface or at the required distance from the magnet. Our instrumentation performs spot measurements as well as mapping of loose-laid magnets or solids with them, as well as while rotating. We are capable of comprehensively analysing the data obtained, checking individual vectors of the magnetic induction, displaying the 3D distribution of the magnetic field around the magnet.
measurement on finished parts
We are capable of checking the distribution of the magnetic field (magnetic induction) not only on permanent magnets themselves but also on products with them, such as magnetic holders, rotors or stators of electric motors, magnetic couplings, magnetic bearings, etc. The measurement of magnetic induction makes it possible to check quality, e.g., for multi-pole magnetised magnets which cannot be measured by means of other available methods.
in our testing laboratory we perform
- measurement of surface induction at a specific point (at a specific distance from the magnet)
- measurement of all 3 components of the resulting surface induction vector (XYZ)
- 3D surface induction mapping of flat solids
- 3D surface induction mapping of solids of revolution
