Manage magnet parameters
How to manage magnet parameters ?
Here is the list of user parameters related to the magnetic behavior of magnets.
| Label | Definition |
| T REF | Reference temperature. |
| Br at T REF | Remanent induction at T REF. |
| α | Reverse temperature coefficient for Br. |
| μ r | Relative permeability. |
| HcJ | Intrinsic coercivity at T REF. |
| β | Reverse temperature coefficient for HcJ. |
| (B.H) max | Energy product. Disabled input field, value deduced from other inputs. |
| Hcb | Normal coercivity at T REF. Disabled input field, value deduced from other inputs. |
| * | Maximum operating temperature. Just for information, not used in computations. |
| * | Curie temperature. Just for information, not used in computations. |

| Presentation of the magnet properties in “Materials” application | |
| 1 | Category dedicated to magnetic properties. Note:
Magnetic properties are linked to the data set in the “Operating
Conditions” (See item 10 for “Operating”) |
| 2 | Input parameters are written in the input area. |
| 3 | Remanent flux density (Br). |
| 4 | Normal coercivity (Hcb). |
| 5 | B(H) curve for the magnet (in blue). |
| 6 | Intrinsic coercivity (HcJ). |
| 7 | Isoline (B.H) max. (in red). |
| 8 | Load line for the defined permeance coefficient (in green) |
| 9 | Operating point for the given permeance coefficient and temperature. |
| 10 | Temperature and permeance coefficient of the magnetic circuit are
defined as “operating conditions” of the magnets. These can be edited in the
dedicated tab “Operating”. Any changes will automatically update the
outputs. Note: These features have no influence in
the magnet physical properties, but these are useful to display its
behavior when working at this operating point. |
