Yes, a magnet can float on a cork in water because the cork provides buoyancy to keep the magnet afloat. The buoyant force of the water supports the weight of the cork and the magnet, allowing them to float together.
The compass needle would be affected by the magnetic field from the nearby magnet. The needle would align itself with the magnetic field of the magnet, causing the compass to point in a direction different from true north.
Yes, it is true that a magnet is an object that can exert force on another material. However, it will only exert that force if it is made out of the correct material. Items made of iron are the most common magnetic objects.
Yes, water waves typically cause objects floating on the surface to move up and down. This is due to the oscillatory motion of the water particles as the wave passes underneath the object, causing it to bob up and down as the wave crest and trough move past.
True. when you heat a magnet you are supplying it with energy therefore the dipoles have enough energy to free themselves form their initial order.
The compass needle is itself a magnet which is why it always points north according to the earth's magnetic field. If you place a magnet (Whose magnetic power is stronger than the earth's) close to the compass its needle will be attracted t the magnet and not to the North Pole.

true Absolutly true Quercus suber is the cork oak.
cause they believed that if a witch floated she was a true witch. if the person sank, they weren't a witch, and also dead to prove it.
Yes, the tree forms a thick, rugged and corky bark. Over time this bark can develop considerable thickness and this can be harvested every 10-12 years as cork. The harvesting of cork does not harm the tree and a new layer of cork regrows, making it a renewable resource.
Then the magnet not only has magnetism, but also an electrical charge.
True for iron filing.
Yes
No.The part of the magnet where there is the strongest pull or attraction are called the poles of the magnet.
They have the strongest magnetic forces :) precious

The cork in the saltwater solution will float higher than the one in distilled water because saltwater is denser than freshwater, providing more buoyancy. The increased density of the saltwater displaces more water, helping the cork float higher.
That statement is not true. Yes a magnet will attract a steel paper clip through air or water. No, a magnetic field will penetrate glass as well... probably. Certain types of glass (which are themselves ferromagnetic) might serve to block a magnetic field.
