Meixiu is at the park with her friend joey from physics class. they want to understand projectile motion, so they are using a pitching machine to launch baseballs, and observe the baseball's trajectories for different scenarios. later, they use this simulation to them understand what they observed.

The field lines around one end of a bar magnet are shown below based on the diagram, what can you conclude about the pole of the magnet? a.is a south pole because the field hnes spread out from this end b.a north pole because the field lines spread out from this end c.a nouth pole because the field lines enter the magnet at this end d.is a north pole because the field lines enter the magnet at this end
