The magnetic force is acting towards 2.
It is given that the diagram below shows a wire carrying a current between the poles of a large horseshoe magnet.
We need to determine in which direction does the magnetic force act on the wire.
We will use Fleming's left hand rule here.
It states that
If we arrange our thumb, forefinger and middle finger of the left-hand perpendicular to each other, then the thumb points towards the direction of the force experienced by the conductor, the forefinger points towards the direction of the magnetic field and the middle finger points.
According to this, the magnetic force is acting towards 2.
Option B is correct.
