Question

Below are field lines for a magnetic field.

Suppose a very long straight wire were held parallel to the plane of the page, as shown. (Assume it extends well past the edges of the figure.) Now suppose the wire is moved toward the top of the page (UP).
Would current through the wire flow to the left, to the right, or not at all? ---Select---To the right.To the left.No current would flow. (right, left, or no cuttent flow)

Suppose instead that the wire were moved toward the left side of the page (LEFT).
Would current through the wire flow to the left, to the right, or not at all? ---Select---To the right.To the leftNo current would flow. (right, left, or no current flow)

Explain your reasoning for your answers to the two questions above.

Explanation / Answer

in both cases there will not be any current.

in the first case the magnetic force on electron will in the page. so they do not move either left are right side.


in the second case the magnetic force on electron will be out of the page. so they do not move either left are right side.
