Home / Examples / Magnetic Analysis (Gauss, Static Analysis/Harmonic analysis) / Example 22: Magnetic Field around Cathode
Magnetic field around the cathode of a sputtering machine is analyzed.
The vectors of the magnetic field and the magnetic flux density are solved.
Unless specified in the list below, the default conditions will be applied.
Results will vary depending on Femtet version and the PC environment.

The vectors of the magnetic flux density are shown below.
The magnetic flux originated from the magnet, placed in the peripheral, flows through the yoke into the magnet in the center.
The vectors of the magnetic field are shown below.
