Question

Suppose that a magnetic field of 1 T goes out of the plane of the page. A straight wire carries a current 1 A from right to left. Find the direction of force acting on the wire.Group of answer choicesout of the pageinto the pageleft, in the plane of the pageright, in the plane of the pageup, in the plane of the page

Answer 1

Given:

The magnetic field, B=1 T

The current through the wire, I=1 A

To find:

The direction of the magnetic force.

Step-by-step explanation:

The direction of the magnetic force is given by the right-hand rule. It states that when you hold the index finger, thumb, and middle finger perpendicular to each other if the index finger is pointing in the direction of a magnetic field and the thumb is pointing in the direction of the flow of the current then the middle finger is will be pointing in the direction of the magnetic force.

By applying this rule, we can see that the middle finger is directed up the plane of the page.

Final answer:

Thus the magnetic field is directed up, in the plane of the page.
