please neatly show all work. diagrams are attached below

The physics of magnetic field lines and two bar magnets side by side. The diagram below shows two bar magnets with the north poles facing each other. . a. Draw a possible magnetic field line pattern for this situation. . b. On the diagram you completed in part a, place a compass in the position shown below. Show how the needle would point. . c. On your diagram, draw an arrow indicating two possible places where a magnetic field vector would point at 450 north of east. Place the two vectors at different distances from the bar magnets, and show how the relative field strength would vary by arrow lengths
