Will pay $20 paypal gift if done correctly, i have the answer to one of these 4 i will post, so better have it right.

 

1) A filament current I = 2.5 A, infinitely long and right lies along the z axis, " free -space " . Find H ( 2,45,0 ) .

 

2) Two filament current, infinitely long and rights are parallel to the z axis, and are located at the points x = 2 and x = -2, respectively, in "free-space". Find H at the point x = 0, if: a) the currents of the two filaments flowing in the same direction; b) if the filaments currents flow in opposite directions.

 

3) A filament current I = 2.5 A, infinitely long and right lies along the z axis, "free-space". Find the magnetic flux Φ, which crosses the surface a) 0 ≤ r ≤ 2, φ = 450, 0 ≤ Z ≤ 2; b) r = 2

 

4) In a magnetic material mr = 3.6 and B = 285 b C / m2 magnetic material; find the magnitude of H
