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.

@ Cheerful Magnetic Clips
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.

@ Magnetised Metal Spheres
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, Magnetic Energy
Saturn, Jupiter, Neptune and Uranus all have their own magnetic fields.

@ Dutch Fridge Magnets
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.

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
The Earth is a large magnet The Earth’s core is made up of mostly iron, which has given the Earth its own magnetic field, with both a north and south-facing pole. The Earth’s magnetic field protects the planet by deflecting solar winds and charged particles from the sun.

Ferrite is a ceramic compound composed of iron oxide and other elements (strontium or barium). Among the applications of ferrites are refrigerator magnets and small electric motors.

"I don't know; what?" responded Ashra.
"A construction site has more poles!"

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.

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.

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

@ Dart Board
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
