Mastering Physics Solutions: Direction of the Magnetic Field due to a Wire Conceptual Question

Direction of the Magnetic Field due to a Wire Conceptual Question

Part A = BA is out of the page.
Part B = BB is into the page.
Part C = BC is out of the page.
Part D = BD is out of the page.
Part E = BE is into the page.

Solutions Below:

Find the direction of the magnetic field at each of the indicated points.

For the following two questions consider the wire shown in the figure. (Intro 1 figure).

Part A

What is the direction of the magnetic field BA at Point A?

  • BA is out of the page.
  • BA is into the page.
  • BA is neither out of nor into the page and BA ≠ 0.
  • BA = 0.

BA is out of the page.

Part B

What is the direction of the magnetic field BB at Point A?

  • BB is out of the page.
  • BB is into the page.
  • BB is neither out of nor into the page and BB ≠ 0.
  • BB = 0.

BB is into the page.

Now consider the wires shown in this figure. (Intro 2 figure) Note that the bottom wire carries a current of magnitude 2I.

Part C

What is the direction of the magnetic field BC at Point C?

  • BC is out of the page.
  • BC is into the page.
  • BC is neither out of nor into the page and BC ≠ 0.
  • BC = 0.

BC is out of the page.

Part D

What is the direction of the magnetic field BD at Point D?

  • BD is out of the page.
  • BD is into the page.
  • BD is neither out of nor into the page and BD ≠ 0.
  • BD = 0.

BD is out of the page.

Part E

What is the direction of the magnetic field BE at Point E?

  • BE is out of the page.
  • BE is into the page.
  • BE is neither out of nor into the page and BD ≠ 0.
  • BE = 0.

BE is into the page.
