Magnet Build

The foundation of the scanner begins with the magnet. Strong N48 neodymium magnets are carefully positioned into circular rings.

Once a full ring is completed, the rings are stacked in a symmetric arrangement. This ensures stability and balanced magnetic geometry.

With the structure in place, the magnetic field distribution is measured. A custom robot scanned 914 points inside a 6 cm diameter sphere to capture detailed field values.

Finally, the data is visualized in 3D. These plots confirm that the magnet design achieves the required homogeneity.
