Me and my dad have never heard of it... What is it? Sincerly -Sheepe | ||

It is how magnets are measured. Magnetic flux (abbreviated B) is measured in Gauss. Magnetic field intensity (abbreviated H) is measured in Oersteds. The strength of a magnet is the product of the two, just as electrical power in Watts is the product of Volts and Amperes. If we were talking about water powering a water wheel, flux would be the amount of water flowing per second (the current), and the field intensity would be the water pressure. A high pressure squirt gun, or a low pressure fire hose would not turn the wheel as well or as fast as a high pressure fire hose. Our magnets have surface fields and field intensityies in thousands of Gauss and thousands of Oersteds, respectively. When multiplied, you get millions of Gauss-Oersteds. The prefix "mega" means million, so a MegaGaussOersted is a million Gauss-Oersteds. Our 48 MegaGaussOersted magnets are the most powerful magnets we have seen from any manufacturer. If we find any more powerful, we will offer them on our web site. | ||

is a N48 magnet the same as a 48Mega-Gauss-Oersted magnet? if so, i saw some N50 magnets on ebay. | ||

Yes. And, as promised, the magnets we offer on the web site are now 50 MGOe, as that technology has recently become available. | ||

so, given a rating of 50MGOe, How do I calculate B? Is there a standard field intensity that is assumed ? | ||
| Simon Quellen Field (Sfield) Senior Member Username: Sfield Post Number: 635 Registered: 12-2004 |
If B times H is 50 MGOe, then you would need to know H to get B. | ||

Do you know the field intensity off hand of your 50MGOe magnets? | ||

I don't get the analogy for the flux and intensity....It makes sense to me with electricity but not magnets. Is there any other explanation? |
