Blue And Copper Egg
The first painted eggs came from Mesopotamia, and because eggs were forbidden food during Lent, people painted eggs while Lent was being observed—after Lent, they would eat the eggs on Easter Day.

Beautifully decorated eggs “pysanka” are associated with Ukraine, and the oldest painted egg that was unearthed in northern Ukraine is dated to the end of the 17th century.

@ Magnetised Metal Spheres
I asked Alexa: "What’s the difference between light and dark soy sauce?"
She replied: "Dark soy sauce is used in Chinese cooking to add colour and flavour to dishes. Light is an electromagnetic radiation within a certain portion of the electro magnetic spectrum."

@ Abstract, Magnetic Energy
Electromagnets are used by some high-speed trains. These trains 'float' above the track, which reduces friction, helping the train to go faster.

"What’s the difference between a magnet and a construction site?" asked Fancy.
"I don't know; what?" responded LoosaAppa.
"A construction site has more poles!"

@ Aurora Borealis Phenomenon
Scientists have shown that Earth’s magnetic field is weakening. Current events have made it less attractive.

Purple and Gold Aurora
Auroras occur when charged particles (electrons and protons) collide with gases in the Earth's upper atmosphere. Those collisions produce tiny flashes that fill the sky with colourful light. As billions of flashes occur in sequence, the auroras appear to move or dance in the sky.

@ Purple and Gold Aurora
All magnets produce a magnetic force: this is called a magnetic field. This field travels from a magnet’s north pole to the south pole and is completely invisible to the human eye, however, iron filings can be used to show these fields.

@ Magnetic Levitation Traiin
Magnetic fields can cause paper clips to become temporary magnets attracting other paper clips. In the absence of the permanent magnet, the paper clips lose their magnetic properties.

@ Abstract Solar System
Alnico is an alloy made up of aluminium, nickel and cobalt. A strong permanent magnet can be made from Alnico alloys. Consumer electronics and industrial applications use them extensively. The material is found for example in large electric motors, microphones, loudspeakers, electric guitar pickups and microwave ovens.

Turquoise Northern Lights
The aurora can be seen near the poles of both the northern and southern hemisphere. In the north the display is known as the aurora borealis; in the south it is called the aurora australis. What we are seeing in these beautiful displays in the sky are atoms and molecules in our atmosphere colliding with particles from the sun. The aurora's characteristic wavy patterns and curtains of light are caused by the lines of force in the Earth’s magnetic field.

@ Turquoise Northern Lights
"Wow! I'm going to get me one of these cool fridge magnets!" remarked Bubblegum.
"Me too!" said LoosaAppa. "It'll be a nice reminder of our Rare Earth experience, won't it?"

@ Old Fashioned Compass
There are different types of magnets
There are three different types of magnets: electromagnets, air-core magnets, and permanent magnets. There are five types of modern permanent magnets, each made in a different way from different materials with different characteristics. The five types of permanent magnets:
Neodymium
Samarium Cobalt
Ferrite
Alnico
Flexible Rubber

"Hey, LoosaAppa—what's the difference between a pessimist and a magnet?"
"I don't know, Boci. What is the difference?"
"A magnet has a positive side!"

Northern Lights in Green
What causes the different colours in the aurora? Different gases give off different colours when they are heated. The same process is also taking place in the aurora. The two primary gases in the Earth’s atmosphere are nitrogen and oxygen, and these elements give off different colours during an aurora display. The green we see in the aurora is characteristic of oxygen, while hints of purple, blue or pink are caused by nitrogen.

@ Physics Wallpaper
Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium, copper and gold, are NOT magnetic.
