| (C) | Out of the page | Away from the wire (\(+y\)-direction) |
| (D) | Out of the page | Toward the wire (\(-y\)-direction) |
Which row in the table correctly indicates the direction of the magnetic field produced by the wire at the electron's position and the direction of the magnetic force exerted on the electron?
