Figure shows a cross section of an infinite conducting sheet carrying a current per unit x length
Question:
Figure shows a cross section of an infinite conducting sheet carrying a current per unit x length of λ; the current emerges perpendicularly out of the page.?
(a) Use the Biot-Savart law and symmetry to show that for all points P above the sheet and all points P' below it, the magnetic field B is parallel to the sheet and directed as shown.?
(b) Use Ampere's law to prove that B = l/2μ0λ at all points P and P??.
Lp B P'. B -X
Step by Step Answer:
The current per unit xlength may be viewed as current density multiplied by the thickness Ay of the ...View the full answer

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. The video shows the practical implications of magnetic force around different objects.
