Saving settings and networks
When a network setup is configured for a specific measurement and /or analysis flow, it can be saved to a specific file, which can be loaded later again.
Read moreWhen a network setup is configured for a specific measurement and /or analysis flow, it can be saved to a file, which can be loaded later again.
To save a network to a file, select Save as… in the network’s context menu:
By default, MagScope will propose to save the file in the ‘C:/ProgramData/Magcam/MagScope/Presets/Custom’ directory. The ‘Presets’ directory is special, since files that are saved in this folder are directly available from the MagScope menu.
MagFit introduction
The MagFit magnet analysis software module offers advanced data analysis capabilities for a complete characterization of uniaxial permanent magnets. By comparing the measured data with theoretical magnet models, MagFit extracts a lot of extra information from the data.

Magnetization vector and angle measurement
The MagFit magnet analysis software module offers advanced Magcam data analysis capabilities for a complete characterization of uniaxial permanent magnets.
Read moreThe MagFit magnet analysis software module offers advanced Magcam data analysis capabilities for a complete characterization of uniaxial permanent magnets. By comparing the measured data with theoretical magnet models, MagFit can extracts the magnet’s full magnetization vector (Mx, My and Mz components) and its deviation angle from the main axis.
The first step in making a MagFit analysis is the measurement of a magnetic field image of the magnet under test using the Magcam magnetic field camera.
Residual image
The output of the MagFit element in the network is the residual image. It can be visualized by adding a 2DPlot or surface Plot
Read moreThe output of the MagFit element in the network is the residual image. It can be visualized by adding a 2DPlot after the MagFit element.
The residual image shows all deviations from the fitted theoretical magnetic field distribution used in MagFit.
On the left is the measured magnetic field distribution. On the right is the same distribution zoomed around the pole value.
In the residual image, shown below, material defects and magnetization inhomogeneities are readily visible.
MagScope basics
MagScope is built around ‘data’ and ‘networks’. Data is a matrix of measurement points, such as the magnetic field distributions that come from the magnetic field camera. The data is processed inside one or more ‘networks’, where it can be displayed, analyzed, transformed etc.

A network is a chain of ‘Elements’ through which the data flows. There are many types of elements and they can be combined in many ways, making the software very modular and flexible. Each element does something with the data (e.g. a ‘Plot’ element visualizes it) and then the data continues through the network to the next element.
Zero crossing detection on a circle
Some applications require to cut out a pole of a ring magnet, but the ring can be arbitrarily oriented along the angular direction, which makes it impossible to know where the poles will be exactly. In the 2DPlot Section cutouts can be defined based on zero crossings that are automatically detected

Opening a data file
MagScope supports two types of data files, CSV files and MCB files (the native MagScope format). To open a previously recorded/saved file, one can select File/Open MCB or File/Open CSV, depending on what type of file you want to open.
Read moreTwo types of data files are supported by MagScope:
- MCB files: the native MagScope format. These are binary files containing magnetic field images. These files can be opened only by MagScope. Their file size is smaller than that of a corresponding CSV file.
- CSV files: ‘Comma Separated Values’ files containing magnetic field distribution data. These files can be opened with other programs, such as Matlab, Excel, Notepad etc.
Note: MagScope is backward compatible with the older ‘.magcam’ file format, as used by earlier versions of MagScope (v.3.x). They can be opened the same way as CSV files.
Creating plots and graphs
MagScope has the ability to show the magnetic field in different plot and graph formats, such as 2D, surface and quiver plots.

2D Plot
The 2DPlot element visualizes the data in a two dimensional color graph. When creating a 2DPlot element the ‘2DPlot’ window is shown. The 2DPlot allows you to draw following plot elements such as lines and circles. Measurements can be made between plot elements of the same type.
From the plot window, cross-sections and 2D areas can be selected and further analyzed in a new network.
Saving measurement data
MagScope provides the option to save measurement data manually (one measurement) or automatically (measurements on multiple magnets).
Read moreMagScope provides the option to save measurement data manually (one or a few measurements) or automatically (measurements on multiple magnets).
Manually
To save the measurement data to a data file, right-click one of the elements in the network, e.g. the Camera element and select Save…:
A dialog is shown that asks the user to which type of file (.mcb or .csv) the data should be saved. Select the desired format.
Both small electric rotors and larger rotors for e.g. electric vehicle (EV) drives are measured with Magcam’s Rotor or Combi Scanner.
For this application the in-plane Bxy field component is important and can be measured with the Magcam MiniCube3D camera.
It is important in this application to measure and analyze if the zero crossings and pole peaks are equal.
The detection of the pole peaks and zero crossings as well as the Fourier harmonics analysis is important in this application.
The MiniCube1D camera instantly measures the Bz field distribution, which is the most important parameter in this application.
With the MagFit SW module, the magnetization vector magnitude and angle deviation can be accurately measured and analysed.
MagFit can filter out the signature of cracks from the background field distribution and automatically detect cracks.
The Magcam systems are very suitable for 100% automated in-line production testing and quality control.
