Yellow Daisy Egg
My pets are in awe of these beautiful eggs—they would love to try to paint their own one year. Easter and spring are times of joy as the earth awakens, plants are pushing forth from the soil, and the days are becoming warmer. Many baby animals are born in the spring, and life is burgeoning. May these eggs bring you joy and be a reminder of the earth renewing itself.

Cheerful Magnetic Clips
Keep your noticeboard in order with these colourful clips!

@ Cheerful Magnetic Clips
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.

@ Magnetised Metal Spheres
Neodymium magnet (NdFeB) is a type of rare-earth magnet that is composed of a neodymium, iron, and boron alloys. General Motors and Sumitomo Special Metals invented them in 1982. The strongest permanent magnets currently available are neodymium magnets. Among their applications are cordless tools, hard disk drives, and magnetic fasteners.

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

@ Dutch Fridge Magnets
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.

@ Aurora Borealis Phenomenon
The unit used to measure the strength of a magnet is called a tesla.

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
"You know, I love talking about magnets. But I try not to."
"Why's that, Kathleen?" asked Choose a name, baffled.
"It's quite a polarizing topic!" responded Kathleen.

@ Magnetic Levitation Traiin
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 Solar System
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

@ Ducks in a Row
What will happen when the Earth's magnetic poles flip? I don't know, but I heard Santa's been interviewing penguins to see if they can pull a sleigh.

@ Itty Bitty Magnets
An electron and a proton walk into a magnetic field... ... Yes. That's it. There's no punchline. Physics isn't a joke.

@ Electromagnetic Waves
Scientists have shown that Earth’s magnetic field is weakening. Current events have made it less attractive.

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
The Earth's magnetic poles move about 40 kilometres each year.

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.

Reel to Reel Tape
Some old-fashioned magnetic tape! Do you remember recording the top hits of the day on a reel-to-reel tape recorder?

@ Reel to Reel Tape
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.
