As we all know, magnets are objects that produce a magnetic force, which is an invisible force that pulls ferromagnetic objects towards itself and attracts or repels other magnets around it.

There are endless uses for magnets in our daily life, like in simple household appliances, cabinet door latches, home audio speakers, and even debit and credit cards.

There are specific objects that are strongly and easily attracted to magnets and are called ferromagnetic objects, like iron, nickel, and cobalt. There are endless things that a magnet can do that most people are unaware of. So, let's learn some things about these magical objects!

How are magnets used in daily life?

Our day-to-day routine involves numerous uses of magnets that we don't even realize.

  • From the minute we wake up in the morning to the minute we sleep, we come across hundreds of magnetically driven objects.
  • From alarm clocks to induction cookers, every small object contains a magnetic field.
  • The credit and debit cards we use have magnetic strips on their side, which contain a user's information that links with an account.
  • Speakers and microphones make use of small permanent magnets that can convert electric energy into mechanical energy.
  • Electricity generators and electric motors use permanent magnets that can convert mechanical energy into electrical energy and vice versa when a conductor is moved through a magnetic field.
  • Home appliances like electric fans, doorbells, cookers, and locks use electromagnets for their mechanisms.
  • Most computer hardware uses magnetic tapes, which employ the principles of electromagnetism.
  • Audio cassettes and VHS tapes contain magnetic tapes that hold video and sound information. Also, floppy disks and hard disks have magnetic coatings that record data on them.

Importance Of Magnets

Most of the dynamic valuables we depend on today use magnetism in them.

  • Magnetism has proved to be one of the most dependable sources of energy as it is free from frequent maintenance and doesn't cost much to generate.
  • The way magnetism is induced in electromagnetic objects has revolutionized the whole energy sector. Almost every object around us uses this energy to work properly.
  • Numerous scientific and technological applications run on magnets and electromagnetic effects.
  • Important sectors, like electronics, industrial, health, and technological fields, wouldn't operate without magnets as they heavily depend on them as an important constituent for electric power generation.
  • Also, the food industry heavily depends on machinery that operates on electromagnetic principles.

How are magnets made?

There are several ways through which magnets are manufactured.

  • The main constituent of magnets is ferromagnetic metals, like iron, cobalt, and nickel.
  • The process behind its manufacture includes arranging the domain of ferromagnetic metals through different methods which align them to create a strong magnetic field.
  • These methods mainly make use of a strong electromagnetic force that can force these metal particles to align in a particular direction.
  • Also, the manufacturing process of magnets depends upon the type of magnet that has to be manufactured, for example, permanent or temporary.
  • The domains are supposed to return to their original positions in the case of temporary magnets, while permanent magnets tend to hold their magnetism longer.
  • When these ferromagnetic metals are heated to the Curie temperature, they gain magnetic properties. This creates temporary magnets, while heating beyond this temperature will create permanent magnets.

Fun Facts About Magnets

The biggest magnet that mankind has ever come across is the planet Earth. It has a north pole and south pole, which work in the same ways as the poles of a real magnet. This is the reason why a compass shows correct directions as it aligns with the Earth's magnetic fields.

  • There are birds and animals that use the Earth's magnetic field to find their direction.
  • The use of magnets has been extended to medical equipment, like MRI machines and magnetic resonance imaging machines and simple ones like vending machines.
  • As you know, MRI machines are commonly used medical equipment in hospitals. Magnets are used in electronic devices and have also taken their place as medicinal magnets.
  • Magnetic fields are quite easy to understand. The basics state that a magnetic material always comes with two poles: the north pole and the south pole.
  • The main difference between these poles is that the north poles attract south poles when you place two magnets or magnetic material in one place, and the south pole also gets attracted to the north pole. They simply attract opposite poles.
  • While the theory of north and south poles contributes to the basic set of magnetic principles, there is an interesting fact that relates this process to sound vibrations.
  • Did you know that sound waves have magnetic properties? Magnets are used for their ability to control heat and sound.
  • The usage of magnetic materials is beyond just the laws of physics. Magnets are used to store computer data.
  • Computers have a tiny yet strong magnet to store information. On the other hand, the hard disk of a computer has metal fragments. This presence helps the computer create photos and music.
  • Similarly, small electric motors and loudspeakers use ferrite magnets for their high coercivity. It is interesting how magnets alter some materials.
  • Your learning process about magnets can start from simply using a magnetic needle or a wire coil under safe circumstances. You don't need a giant magnet and magnetic sorting machines to explore magnetism. We hope this article gives you an overview of how easily you can learn about and use magnets.
