Caleb as an idea to cut a bar magnet in half so that he can have one magnet with a north pole and one magnet with a south pole. What is wrong with this idea?

Why is earth's outer core hotter than earth’s oceanic crust? earth’s oceanic crust is denser than earth’s outer core is. earth’s oceanic crust has lava flowing from the mantle. earth’s outer core has a composition of solid iron and nickel. earth’s outer core is deeper within earth than oceanic crust is.
