Magnetic 
Field Strength Calculator  
 
Quick. 
  
Whats the field strength one inch from the face of a 6 mm diameter, 
4 mm long Ceramic 8 magnet? 
 
You could dust off Maxwells equations and do some multivariate calculus. 
 
 
Or you can download our Flux 
Density Calculator Excel spreadsheet. 
 
The spreadsheet calculates magnetic field intensity in Oersteds from a disk or 
bar magnet at various distances. It's invaluable for the design of magnetic sensor 
systems, and it can also make you the life of any party.

RS-485 
A/B Naming Conventions  
  
Q. The PROFIBUS and RS-485 standards define A as 
inverting (-) bus connection and B is non-inverting (+), but NVEs 
isolated transceiver datasheets are the reverse. 
 
What gives? 
 
A. Unfortunately there is no consistency in the industry on whether A or B are 
inverting or non-inverting. Most transceiver ICs use the reverse naming convention 
from the PROFIBUS and RS-485 standards. 
 
We follow the transceiver chip convention because many of our customers are replacing 
non-isolated transceiver ICs. 
 
The confusion is unfortunate, but changing datasheets would be more confusing.
