All About Magnets

A magnet is a piece of iron that has its component atoms so ordered that the material exhibits properties of magnetism, such as attracting other iron-containing objects or aligning itself in an external magnetic field. Magnetism physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects. Some magnets only work in another magnets magnetic field, these are called temporary magnets. A permanent magnet always works.

Electromagnets and Superconductors and Other Facts

Electromagnets are, a soft metal core made into a magnet by the passage of electric current through a coil surrounding it. Superconductors are, a substance capable of superconducting at low temperatures. Interesting fact the man who discovered magnets name was magnes. Did you know all magnets have north and south poles,and attract iron. Other planets have magnetic fields these include, Mars, Venus, Jupiter, Saturn, and Neptune.

10 Uses for 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 onto the workshop floor.

Magnets make life easier by finding metal items that have fallen
