3.2.1 Bar

Figure 3-4 Bar Magnet

The standard dipole bar magnet is created by selecting "Bar" from the "Magnet Shape" dropdown menu and leaving the pole count at 2. This populates the "Magnet Geometry" fields and prompts the user to enter length, width, and height of the magnet. These parameters are drawn, respectively, in X, Y, Z order.

Figure 3-5 Bar Magnet Input Fields

Magnet orientation defaults with the North pole directed in the positive Z-direction. It may be necessary to perform a rotation to orient the magnet to match the target system. In this event, rotations may take place about each axis in X->Y->Z order.

For instance, to obtain a 2 mm thick bar magnet that is 3 mm wide and 5 mm long, but polarized in X, the settings shown in #GUID-DF5D77B8-5C36-4BC8-972B-91172D397C89 may be used.

Figure 3-6 Rotated Bar Magnet

Bar magnets are ubiquitous and found commonly across many applications. Their simple shape and polarization result with a typically inexpensive option that is easy to orient during product assembly.
