Final answer:
The claim that a magnetic pickup will attract any kind of metal is false; magnets attract only certain metals like iron, nickel, and cobalt, but not nonmetals. A magnet's north pole will point toward the Earth's magnetic north pole, and each piece of a shattered magnet will have north and south poles. Dropping a magnet through a copper tube induces eddy currents.
Step-by-step explanation:
The statement that a magnetic pickup will attract any kind of metal is false. Magnetic pickups, or magnets in general, can attract ferromagnetic materials such as iron, nickel, and cobalt. However, they do not attract all metals, and nonmetals like plastic or wood are also not attracted by magnets. Regarding the behavior of a magnet, if it's elongated and free to rotate, its north pole will orient itself toward the magnetic north pole of the Earth, not the magnetic south pole. Additionally, if a magnet is shattered, each piece will indeed have its own north and south poles, making this statement true. Furthermore, if you drop a bar magnet through a copper tube, it induces electrical currents in the tube called eddy currents, which create a magnetic field that opposes the magnet's motion, validating that this statement is also true.
