History

1. horseshoe magnets are stronger than the bar magnet because of its shape. The poles of a horseshoe magnet are pointing in the same direction and this creates a strong magnetic field. Therefore, horseshoe magnets are used to lift heavy objects. 2. When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart (repel).

3. earthquakes — we now know that most quakes are caused by tectonic processes — forces within the solid Earth that drive changes in the structure of Earth's crust, primarily the rupture of underground rock masses along faults (linear zones of weakness).
