Some Animals Have Magnets? Five Fascinating Facts About Magnets That Will Wow You

Magnets are one of the coolest pieces we played with as children. The fact that metal can attract another was so fascinating. The best part was when it repels a similar edge of another magnet. People now apply the line “unlike poles attract and like poles repel” to pretty much everything else. We began to find them again in dismantled radio sets and old wrecked machines and we would pick pieces to see how many more things it can attract.

These pieces of metal are a basic component of many everyday gadgets. Many people even use them to find metals and store pins and needles. They are also used to decorate things on our fridges. A major trip down memory lane would be those fruit magnets that were a staple on every Nigerian family’s refrigerator.

 

It will be worth knowing these metals more with these five cool facts.

 

1. Magnetism Is Light

Magnets

 

The reason magnets attract each other is that they exchange photons. Photons are the particles that make up light. However, unlike visible photons in light, these are invincible and cannot be seen with the n***d eyes. A key feature they have is that they can exchange momentum which is what makes them attract or repel. Photons are the force carriers for electrostatic phenomena like static electricity.

 

2. The Most Powerful Magnets Are In America

Magnetic

 

America is home to the biggest magnets in the world. They live at Los Alamos National Laboratory in New Mexico and Florida State University. The magnets are the gigantic ones that lift cars and can lift 2 Tesla vehicles. While one magnet is designed to generate fields that last only a few seconds, the other maintains its fields for as long as the power is on.

 

They are designed to perform different experiments. Interestingly, staying in the same room as magnets can have catastrophic effects. This is because every pulsed magnet will eventually destroy itself because of the stresses of the magnetic forces on the coils.

 

3. Magnets Come In Four Flavours

Magnets

 

Ferromagnets have a substance composed of atoms with unpaired electrons. Their spins align, and then they make good permanent magnets. They include substances like Nickel and Iron.

 

The other type is the ferrimagnets, where only some of its electron spins align.

 

Paramagnets are mostly found in chemical elements. They magnetise only when in another magnetic field, and they also boost unpaired electrons.

 

Diamagnetic materials are best for lifting objects to float in the air. They magnetise when in a field and they generate fields opposite the one which they are located.

 

4. Some Animals Have Magnets

Pigeons

 

Certain bacteria and animals have magnetite in their bodies. Some have magnetite in their teeth and they are mostly abrasive. It lets the animal scrape algae and feed effectively. Pigeons are also said to have a magnetic sense that helps them navigate. Even though it is an important part of the bird’s beak, the magnitude of its role remains unclear.

5. Magnets Aren’t Always Metal

Fridge Magnet

 

Most of the metals we use comprise of iron, but they don’t always come in that form. Magnets comprise of any material with unpaired electrons. That means they could be anything from metals and alloys used for disk drives to other substances. In fact, most ferrimagnetic materials are not metals at all. An example would be them “Coldstone” magnet stickers for refrigerators that feel almost rubbery.
