Whales have a much lower density than a magnet. Or another way of putting it, whales are more buoyant. Density is like a mixture of mass and volume. Lets say you have a 1000 pound whale, and a 1000 pound magnet. Their weight(mass) is the same, but the amount of the space they are taking up(volume) is different. Just think of it like there are more air pockets in a whale than in a magnet, causing the magnet to sink but the whale to float.
A magnet would typically sink in water as it is denser than water and does not have the buoyancy to float.
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.
Although it does not appear to be magnetic, water, like all matter, may display magnetic characteristics when exposed to a large enough magnetic field. A extremely powerful magnet repels water by a little amount. You may do this yourself if you have a neodymium magnet.
Simply hover the magnet over the mix and all the iron shreddings should float up to the magnet because of its attraction to it.
duckweed is small and can float easily
Bring a compass in the vicinity of your magnet Put it on a float in water
Fill the container about half full of water. Float a leaf on the surface of the water, and float the needle on the leaf. That'll be a beautiful demonstration. I think I'll make one, and I thank you for the idea.
Yes, a pin can float on water due to its low density and small surface area. Surface tension of water helps support the weight of the pin, allowing it to float.
the modern iron has a small "shell" to hold the water in it now if its empty and is in water it may float from the air inside the iron
The fuel float will float in water but not fuel because it has a small leak in the float. Water and fuel have difference densities, and the leak is likely small enough to let fuel in, but not water. For an 88 Bronco, the part you are looking for is COAZ-9202-B
Yes, if the density of the salted water is sufficiently great.
Insects can float on water due to their small size and surface tension of water. Their lightweight bodies and small surface area allow them to be supported by the water's surface tension, which is the result of water molecules sticking together. This allows insects to walk on water without sinking.
