No, a tennis ball is not magnetic. It is primarily made of rubber and covered with a layer of felt, neither of which are magnetic materials. Therefore, a tennis ball will not be attracted to magnets or exhibit magnetic properties.
Ball bearings are not typically magnetic, as they are usually made of non-magnetic materials like steel. However, some ball bearings can be made with magnetic properties for specific applications. The magnetic property of ball bearings can affect their performance in machinery by influencing their ability to attract or repel other magnetic materials, which can impact their movement and stability within the machinery.
Ball bearings are typically made of steel, which is not a magnetic material. They will sink in water and not float because their density is higher than that of water. If exposed to a strong magnetic field, ball bearings made of magnetic materials like iron may be attracted to the magnet.
no
yes it is possible. if we take a magnet and get close to the ball having magnetic properties but not too close (if too close it will stick together) we can make the ball to rotate.
yes
no because they are not magnetic and their not made of magnet
If a single magnetic ball is swallowed, it may pass through the digestive system without causing harm. However, if the magnetic ball is strong and attracts to another object in the digestive tract, it could cause a blockage or tissue damage, requiring medical intervention to remove it. It is important to seek medical attention if a magnetic ball is swallowed to prevent complications.
A magnetic ball pocket is used on many pool tables, especially ones that charge per play. It will ensure that the balls are collected after they are sunk.
Graphite is not magnetic as it is made out of carbon. E.g; Pencil lead is mostly made out of graphite, it is NOT magnetic.
If you mean the magic trick, you have to give a regular ball to your "assistant", get them to see the ball falling, then palm a different ball which has a magnetic charge on it, it will seemingly "slide" through the tube as it's weight over-rides the magnetic pull of the ball by the tube
Oil is not magnetic, but magnetic substances can be made from it.
