I know that magnets are attracted to iron. I don't know the proccess of how magnets stick to something. I also need to know more sciency magnet words like magnetism and ferrous.like that. what is magnetism. stuff like that. i need help because I might fail the pssa. i don't want to.
later on i might post again to need help on the unit of electricity.
thanks ms.sue, your always there for me! =) <3

I'm here to help you understand magnets and magnetism! Let's start with the basics.
Magnetism is a natural force that causes certain materials to be attracted to or repelled by magnets. It is the property of materials that creates a magnetic field, which is an invisible area around a magnet where its magnetic force can be felt. Magnets have two poles, a north pole and a south pole. Like poles repel each other, while opposite poles attract each other.
Magnets can stick to certain materials due to a property called ferromagnetism. Ferromagnetic materials, like iron, nickel, and cobalt, are strongly attracted to magnets. When a ferromagnetic material comes near a magnet, the magnetic field of the magnet aligns the domains (tiny magnetic regions) within the material, causing it to be attracted to the magnet.
To understand the process of how magnets stick to something, it's important to know that there are two types of magnetic materials: permanent magnets and temporary magnets. Permanent magnets, like those you might find in a fridge magnet, are made from materials that retain their magnetism even when not in the presence of a magnetic field. Temporary magnets, on the other hand, only exhibit magnetism in the presence of a magnetic field.
When a permanent magnet comes into contact with a ferromagnetic material, the alignment of the domains causes the ferromagnetic material to become temporarily magnetized. This temporary magnetization allows the two objects to stick together. However, it's important to note that not all materials are attracted to magnets. Materials like plastic, wood, or glass are not magnetic and will not stick to magnets.
Now that you have a basic understanding of magnetism, you can explore more scientific terms related to magnets. Here are a few:
1. Magnetic field: The region around a magnet where its magnetic force can be felt.
2. Magnetic force: The force of attraction or repulsion between magnets or magnetic materials.
3. Electromagnetism: The relationship between electricity and magnetism. When an electric current flows through a wire, a magnetic field is created around the wire.
4. Magnetic induction: The process of creating a temporary magnet in a material by bringing it close to or in contact with a magnet.
5. Magnetic poles: The ends of a magnet, usually identified as North (N) and South (S) poles. North attracts the South and repels another North, while South attracts another South and repels a North.
If you have any more questions or need further help, feel free to ask. Good luck with your studies and the PSSA! I'll be here to assist you.
