Question
Hello!
I've been trying to figure out this question and I still seem to be coming up with the wrong answer. Any help would be appreciated !

Transcribed Image Text:**Magnetic Fields and Wire Interaction**
---
**Question Overview:**
Suppose in the drawing that \( I_1 = I_2 = 54.1 \, \text{A} \) and that the separation between the wires is \( 0.0390 \, \text{m} \). By applying an external magnetic field (created by a source other than the wires), it is possible to cancel the mutual repulsion of the wires. This external field must point along the vertical direction.
**Questions:**
- **(a)** Does the external field point up or down?
- **(b)** What is the magnitude of the external field?
**User's Response:**
- **(a)** The external field points: *downward*
- **(b)** Number: *220.776* Units: *T*
**Diagram Explanation:**
The diagram illustrates two parallel wires, labeled as Wire 1 and Wire 2. Each wire carries a current (\( I_1 \) and \( I_2 \)) flowing in the same direction. The wires experience a mutual repulsion because of the magnetic fields they create. An external magnetic field is needed to counterbalance this repulsion. The diagram likely shows the direction of the external field and the repulsive forces.

**Note:**
Ensure that you understand the principles of magnetic fields and how they interact with current-carrying wires. This setup demonstrates how an external field can be used to negate forces between wires, a crucial concept for electrical engineering and physics.
