The reaction of boys to magnets can vary depending on their prior knowledge and interest in science. Some boys may be fascinated by the concept of magnetic fields and the interactions between magnets and objects, leading them to experiment and explore further. Others may be less interested and simply observe the effects of magnets without delving deeper into the underlying principles. Overall, exposure to magnets can spark curiosity and encourage hands-on learning experiences in boys of all ages.
CFC's have caused holes to appear. They react with ozone and deplete it.
Magnets attract magnetic materials such as iron. Magnets either attract or repel other magnets depending on the polarity. Magnets repel diamagnetic materials. Most diamagnetic materials (bismuth, diamond, graphite, silver) are only weakly repelled. Super conductors are strongly diamagnetic, and are more strongly repelled.
No. Magnets can pull other magnets towards them, or push them away from them. If a magnet's north pole points towards another magnets north pole (or a south pole towards a south pole), they will repel, instead of pulling them towards them. On the other hand, if a magnet is brought near a piece of iron that is not already magnetic, it will induce magnetism in the iron, in such a way that the two magnets will attract one another. Yet on the other hand, magnets have hardly any influence on most substances.
CFC's are the main substances which cause ozone hole. They react with ozone and decompose it.
To understand this we need to understand the magnetic properties of material. There are 3:-Ferromagnetic.Paramagnetic.Diamagnetic.Ferromagnetic substances which are easily attracted to magnets. Paramagnetic substances are those which are weakly attracted to magnets. Diamagnetic substances are not attracted to magnets. So Palladium falls in the third category while iron is ferromagnetic.
they repel each other
No, magnets do not react to Kevlar because Kevlar is not a magnetic material. Magnets only attract materials that contain iron, nickel, or cobalt. Kevlar is a strong and heat-resistant synthetic fiber used in body armor and other protective gear.
magnets can
React to the nearby presence of another magnet
They will repel each other. You can experiment with this by using children's magnets. These have a painted north and south poles.
Astronauts didn't discover black holes....

It contains a chemical called lame
To prevent causing holes in ozone layer, we must stop the use of CFC's. They react with ozone to deplete it.
