Neodymium magnets

Magnetized and Physical Faculties Many grades of Neodymium magnets exist to support a variety of professional applications. The range of Neo grades typically expands from 33 MGOe to 52 MGOe. This range permits optimizing cost, performance, and working heat weight. The typical convention for “Grade” is by using the worthiness of particular magnet alloy’s Energy Density or optimum Energy Product. Frequently, there are letters or a-two digit quantity suffix connected to the level which shows the Intrinsic Coercive energy (Hci) standard of the magnet alloy. This Hci is an excellent indicator regarding the maximum permitted temperature a particular Neo alloy can tolerate before irreversible demagnetizing does occur. The higher the “Grade number,” the greater the vitality Density. Frequently, the bigger the Energy Density, the more powerful the magnet, but this will be very much based mostly on the magnet’s functional environment. * optimum working Temperature with this Group is 60°C / 140°F ( L/D ≥0.7) Dura Magnetic Level Common Industry Notation Residual Induction Br Coercive Energy Hc Intrinsic Coercive Force Hci Optimum Energy Product (BH)max Range Minimum Minimal Number k-Gauss Tesla k-Oersted kA/m k-Oersted kA/m MGOe kJ/m3 5011 N50 14.0 - 14.5 1.40 - 1.45 10.5 836 11 876 47 - 51 374 - 406 5211 N52 14.4 -14.8 1.44 - 1.48 10.5 836 11 876 49 - 53 390 - 422 * optimum Operating Temperature because of this Group is 80°C / 176°F ( L/D ≥0.7) Dura Magnet Grade Typical Business Notation Residual Induction Br Coercive Energy Hc Intrinsic Coercive Force Hci Maximum Energy Item (BH)max 3512 N35 11.8 - 12.3 1.18 - 1.23 10.9 868 12 955 34 - 36 263 - 287 3812 N38 12.3 - 12.6 1.23 - 1.26 11.3 899 12 955 36 - 39 287 - 311 4012 N40 12.6 - 12.9 1.26 - 1.29 11.4 907 12 955 38 - 41 302 - 327 4212 N42 12.9 - 13.3 1.29 - 1.33 11.5 915 12 955 40 - 43 318 - 342 4512 N45 13.3 - 13.7 1.33 - 1.37 11.0 876 12 955 43 - 46 342 - 366 4812 N48 13.7-14.1 1.37 - 1.41 10.5 836 12 955 45 - 49 358 - 390 * optimal working Temperature because of this Group is 100°C / 212°F ( L/D ≥0.7) Dura Magnet Grade Typical Business Notation Residual Induction Br Coercive Energy Hc Intrinsic Coercive Power Hci Optimum Power Item (BH)max Number Minimum Minimal Range k-Gauss Tesla k-Oersted kA/m k-Oersted kA/m MGOe kJ/m3 3314 N33M 11.3 - 11.8 1.13 - 1.18 10.5 836 14 1,114 31 - 34 247 - 271 3514 N35M 11.8 - 12.3 1.18 - 1.23 10.9 868 14 1,114 34 - 36 263 - 287 3814 N38M 12.3 - 12.6 1.23 - 1.26 11.3 899 14 1,114 36 - 39 287 - 311 4014 N40M 12.6 - 12.9 1.26 - 1.29 11.6 923 14 1,114 38 - 41 302 - 327 4214 N42M 12.9 - 13.3 1.29 - 1.33 12.0 955 14 1,114 40 - 43 318 - 342 4514 N45M 13.3 - 13.7 1.33 - 1.37 12.5 995 14 1,114 43 - 46 342 - 366 4814 N48M 13.7 -14.1 1.37 - 1.41 12.9 1,027 14 1,114 45 - 49 358 - 390 5014 N50M 14.0 - 14.5 1.40 - 1.45 13.0 1,033 14 1,114 47 - 51 374 - 406powerful arc magnet What's more, when the magnet is placed into an outside attractive field, created by an alternate source, it is dependent upon a torque tending to arrange the attractive minute parallel to the field. powerful arc magnet These incorporate the components iron, nickel and cobalt and their compounds, some combinations of uncommon earth metals, and some normally happening minerals, for example, lodestone. powerful arc magnet A magnet is a material or item that creates an attractive field.
