You may have heard a number of things about magnets. Some of these may be true, while others may be false, and we’re sure you may have even more questions.
How can you further your knowledge of magnets? How do they work? What are the benefits of using them in our everyday lives?
The more you learn about magnets, the easier your life will be. For instance, you may replace all of your refrigerator’s family photographs with a strong magnetic strip, taking no time at all!
To answer the question, “How do magnets work?” Just keep reading for some helpful information to get you started.
How Are Magnets Made
The science of magnets says that they are objects that have a magnetic field. This magnetic field is usually created by the action of electrons.
Electrons are tiny particles that orbit around the nucleus of an atom. Some materials, like iron, cobalt, and nickel, have electrons that spin in the same direction. When these electrons spin in the same direction, they create a magnetic field.
The Three Different Types of Magnets
There are three different types of magnets: permanent, electromagnets, and temporary magnets. Here are those.
The first one is permanent magnets. These are usually made from materials that have magnetic properties naturally, like iron.
The magnetic force is created by the electrons in the atom’s outermost shell. When the electrons spin around the nucleus in the same direction, they create a magnetic field.
Second, there are electromagnets. These are usually made from materials that are not naturally magnetic but become magnetic when an electric current is passed through them. The magnetic field is usually created by the electric current flowing through the wire.
Third, there are temporary magnets. It can be turned on and off. They are only magnetized when they are in a magnetic field.
The North and South Poles
Every magnet has north and south poles. Opposing poles are attracted to one another, whereas identical poles repel each other.
When you scratch a piece of iron along a magnet, the north-seeking bars of the atoms in the iron line up in the same direction. A magnetic field is generated by the force created by the aligned atoms.
The Usefulness of Magnets in the Modern World
Do you ever wonder how magnets work on your fridge? It’s actually pretty simple. They are usually made of a material called magnetite.
When you rub a piece of magnetite on a piece of iron, the magnetite aligns itself in the same direction as the Earth’s magnetic field. On the magnet, this alignment produces a north and south pole. When you bring two magnets together, the opposite poles will attract each other, while the same poles will repel each other.
This principle of attraction and repulsion is what makes magnets so useful. For example, trains and cars use magnets to create a magnetic field that propels them forward.
Magnets are also used in MRI machines and speakers. So next time you’re using a magnetic backing, think about the amazing science that makes it work!
Fun Facts About Magnets
Magnets are objects that produce magnetic fields and can attract or repel other objects. They are usually made of materials that have unpaired electrons, and the magnetic field is created by the movement of these unpaired electrons. They can be permanent or temporary, and the strength of the magnetic field depends on the type of material and the shape of the magnet.
