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 strength)=I(current)/A(area)
A(area)=Pi*r(radius)2
L(inductance)=Ioda(magnetic flux)/I(current)
Ioda(magnetic flux)=V(velocity)xT(time)
(permeability)=L(inductance)/d(diameter)
The Attempt at a Solution
Area = 50.24 = (3.14 *(42))
Magnetic Field Strangth = .299 or .3 = (15/50.24)
From this point I am lost because it appears to me that I am missing a key part to finish the equation. If I can find out the time or the charge then I can do some substitions and find the answer the equation. Can anyone point me in the right direction?
These are the possible answers:
1. 1.68 x 10^-5 Wb/meters squared
2. 2.36 x 10^-5 Wb/meters squared
3. 1.68 x 10^-4 Wb/meters squared
4. 2.36 x 10^-4 Wb/meters squared
5. 2.87 x 10 Wb/meters squared
