Cork is wood, therefore it is not magnetic.
A corkboard is board that is made from cork. It is manly used for bulletin boards or presentation boards. Newer versions are not made of cork anymore. They are magnetic and made of metal.
no the cork will sink
To make your own magnetic compass, you will need: a magnet, a small piece of cork, a needle, a container of water, and a paperclip. Rub the needle against the magnet to magnetize it, then insert the needle into the piece of cork. Place the cork in the container of water and wait for it to settle - the needle will align itself with the Earth's magnetic field, indicating the north-south direction. You can use a paperclip to mark the north end of the needle for easy reference.
When a magnetized needle is placed on a cork floating in water, it aligns itself with the Earth's magnetic field. This allows the needle to point north-south, making it a simple compass. The buoyant force from the cork keeps the needle afloat without sinking.
If a magnet is "left to float freely", it will align to any magnetic field - or more precisely, to the horizontal component of the magnetic field. And if there is no stronger magnet nearby, this field will be governed by Earth's magnetic field.
Cork comes from a cork tree :]

To make a magnetic floater, you will need a magnetic material like neodymium magnets, a non-magnetic floating material like cork or foam, and a container filled with a liquid like water or oil. Place the floating material on the liquid's surface and add the magnets underneath to create a magnetic field that holds the float in place. Adjust the strength and positioning of the magnets to achieve the desired floating effect.
If a magnet is floated on a cork in water and balanced on a sharp end, it will align itself with the Earth's magnetic field. One end of the magnet will point toward the magnetic north (which is actually near the geographic south pole) and the other end will point toward the magnetic south. Therefore, if one end points east, the other end will point west, but this is not a typical alignment; usually, it aligns north-south. The orientation depends on the specific magnetic properties of the magnet used.
cork is a type of color like brownish
Cork for bottles is made from cork trees.
