Why does a compass needle get deflected when brought near a bar magnet

compasses use the magnetic attraction of north to show which direction you are going, putting one near a magnet will mess with the magnetic attraction it has to north making it go the wrong direction

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
