World Magnets


What is magnetism

Magnetism is the chemical element of atomic number 12.

What are magnets

Magnets are a piece of iron that has its component atoms so the properties of magnetron or that the material exhibits.

What are temporary magnets

Lose their magnetism when magnetic field disappears.

What are permanent magnets

A magnet that retains it's magnetic properties

What are eletromagnets

A soft metal core made into a magnet by the passage of electric current.

What are superconductors

A substance capable of becoming a superconductor.

Who discovered magnets

The Greeks discovered naturally occurring magnets of magnetite in Turkey.

Four facts about magnets

1)Magnetic forces attract only magnetic materials.2)Magnetic forces act at a distance.3)While magnetized, temporary magnets act like permanent magnets.4)Putting iron inside a current-carrying coil increases the strength of the electromagnet.

10 uses of magnets

1. Locate metal studs in a wall.

2. Seal off air-conditioning vents to improve home heating by placing vinyl-coated sheets over the steel register faces.

3. Hang Polaroids of projects-in-process on the lip of a metal shelf above the workbench.

4. Collect nails from a porch repair job that have fallen in the grass.

5. Prevent corrosion inside your water heater; a magnet placed on the freshwater intake pipe catches damaging metallic calcium particles before they can get inside.

6. Pin blueprints onto the side or hood of the truck.

7. Create a bulletin board without the use of tacks, tape, or hooks on walls coated with "magnetized" paint containing metals.

8. Protect a tractor's engine: Ceramic magnets placed in the oil pan will attract steel bits that get into the oil from grinding pistons.

9. Fasten steel framing squares to the outside of toolboxes for quick access by gluing magnets to the box sides.

10. Clean up metal shavings that have fallen from the bench grinder onto the workshop floor.

How do magnets make life easier or better

Magnets (both permanent and electrical) are used in speakers to reproduce sound so you can hear what it sounds like when doves cry. Magnets are pretty handy in magnetic resonance imaging (MRI) that show where your brain tumor is. Magnets are used in most electrical motors so your little beanie propeller can spin around. Billions of magnets make a hard drive. You can swipe a magnet across a florescent lamp to relight it. Some magnets help you bring back lost family members. Electromagnets cause embedded structures in liquid crystal displays to rotate leading to a dark area that we call a pixel. You may or may not be a magnet. This may or may not make your life easier.
