Magnetic Force

A magnetic force arises when a charged particle or a current-carrying conductor is placed in a magnetic field. It is created because of the movement of the charged particles.

**Problem Description:**

Four long wires are perpendicular to the \( x\text{-}y \) plane. Each wire carries the same magnitude current.

- **Wire 1** goes through point \((a, a, 0)\) on the \( x\text{-}y \) plane.
- **Wire 2** goes through the point \((-a, a, 0)\).
- **Wire 3** goes through the point \((-a, -a, 0)\).
- **Wire 4** goes through the point \((a, -a, 0)\).

Wires 1 and 2 carry their currents in the positive \( z \) direction and wires 3 and 4 carry their currents in the negative \( z \) direction.

**Question:** What is the direction of the resulting magnetic field at the origin?

**Options:**

- ○ the \(-x\) direction
- ○ There is no direction since the field is zero at this position.
- ○ the \(-y\) direction
- ○ the \(+x\) direction
