Detailed Solution

Concept: When a current-carrying captain is in a magnetic field, the magnetic field exerts a pull on it. The Fleming Left Hand Rule can be used to set up the direction of force operating on the captain.
According to the diagram, the thumb points in the direction of force, the middle cutlet points in the direction of the current, and the indicator cutlet points in the direction of the magnetic field.

As seen in the figure, all of the lines are at right angles (90 degrees).
As a result, we can calculate the direction of the magnetic induction-related force.
So, while the current is flowing in the positive direction of the x-axis, the magnetic field is flowing in the positive direction of the y-axis, according to Fleming's right hand rule.
According to the Fleming right hand rule, the magnetic field will be orientated in the positive direction of the x-axis if the current is oriented in the positive direction of the y-axis.
Hence, the correct option is 2.
