(N/A) To determine the direction of the magnetic field,we use Fleming's Left-Hand Rule.
According to Fleming's Left-Hand Rule,if we stretch the thumb,forefinger,and middle finger of our left hand such that they are mutually perpendicular to each other,then:
$1$. The forefinger points in the direction of the magnetic field.
$2$. The middle finger points in the direction of the current.
$3$. The thumb points in the direction of the force on the conductor.
In the given figure,the current is directed towards the left and the force on the conductor is directed upwards.
By applying Fleming's Left-Hand Rule,we find that the magnetic field is directed out of the page (towards the observer).
