can no one help me out?

Homework Statement Someone else posted up this image on yahoo answers and my question is very similar except the numerical figures are different really. http://s3.supload.com/free/Picture_258.jpg/view" How can i solve for for the flux density at the point using the 3-A current...

Yeha I am not exactly sure how any of this works because I missed the last 2 classes and I am playing catch up and it sucks but the list of equations that I originally found were the ones I listed and they didnt help me in anyway but after doing some reading I found the equation that I used in...

QUESTION AND EQUATION ANSWERED! B = permeability x current / 2 x radius B = (4Pi x 10^-7) x 15A / 2 x (.04 meters) B = 2.355 x 10^-4 (rounded off = 2.36 x 10^-4)

After doing some more investigation, I tried another avenue but to no avail. Permeability = 4Pi x 10^-7 H/m (IN A VACUUM) B(magnetic flux) = H(magnetic field strength) * permeability B = .3*(4Pi x 10^-7) B = 3.768 x 10^-7 But it is not the answer according to my instructor...he gave me a list...

Well I was given no equations to work with because i missed this day in class and I am playing catch up so I am lost. These were the "relevant" equations that I could find. I am going to have to look up Biot...appreciate the possible direction point!

can no one show me what it is that I am missing in this problem?

That en lies my problem... For that equation, I need to find permeability! To find permeability I need to find inductance To find Inductance I need to find magnetic flux To find magnetic flux I need to find velocity and time! How am I to find 2 items to which I am unable to derive a...

Homework Statement Loop like an "O" with current moving to the left Diameter = 8cm Current = 15A FIND THE FLUX DENSITY OF THE CURRENT LOOP IN THE PLACE OF THE LOOP? Homework Equations B(flux density)=F(magnetic flux)/A(area) B=H(magnetic field strength)*Permeability H(magnetic field...
