What is the answer?
### Magnetic Induction and Motion

#### Diagram Explanation:
The diagram below illustrates a straight wire positioned at rest within a uniform magnetic field. The magnetic field is represented by several 'X' symbols arranged in a grid pattern, indicating that the field is directed into the plane of the page. The straight wire is drawn vertically at the center of this arrangement.

#### Question:
A potential difference will be induced in the wire if it is moved in which of the following directions?
1. Toward the top of the page
2. Toward the right of the page
3. Into the page
4. Out of the page

**Correct Answer:** (2) Toward the right of the page

*Explanation:* According to Faraday's Law of Induction, a potential difference (voltage) is induced in a conductor when it experiences a change in magnetic flux. In this scenario, moving the wire to the right (perpendicular to the magnetic field lines) would change the magnetic flux through the wire, thereby inducing a potential difference.
