4
H= magnetic field intensity [A/m] B = magnetic field density [Teslas]

5
Biot-Savart Law States that:

6
Example For an infinitive line filament with current I ( 1 =180 o and 2 =0 o ): 2 1 a

7
PE. 7.1 Find H at (0,0,5) Due to current in (figure): where 1 =90 o and 10A 1 y z x 1 (0,0,5)

8
Amperes Law Simpler Analogous to Gauss Law for Coulombs For symmetrical current distributions

9
Amperes Law We define an Amperian path where H is constant.

10
Infinitely long coaxial cable Four cases: 1) For <a z

11
Infinitely long coaxial cable Four cases: 2) For a< <b z

12
Infinitely long coaxial cable Four cases: 3) For b< <b+c z

13
Infinitely long coaxial cable Four cases: 4) For >b+c

14
Sheet of current distribution K [A/m] b a x z y Cross section is a Line! The H field on the Amperian path is given by:

15
PE. 7.5 Sheet of current Plane y=1 carries a current K=50 a z mA/m. Find H at (0,0,0). K =50 -x y z
