In case you didn’t know, the universe is a terribly hostile place for most lifeforms. At least, it is if you don’t have proper protection. Take our own star, for example. The Sun gives life to everything on Earth, but it is also a violent inferno that shoots off high energy particles that could seriously disrupt Earth’s natural systems.  Fortunately, for us, our planet has protection. Ultimately, the Earth is encased in a magnetic field, which is generated by the rotating, liquid iron core…

"A Treatise on Electricity and Magnetism" by James Clerk Maxwell, 1873 Physics nerds pride themselves on wearing T-shirts with Maxwell's equations. The equations' discoverer, Scottish physicist James Clerk Maxwell, compiled his theories into "A Treatise on Electricity and Magnetism," published in 1873.

Magnetic Fields of Venus, Earth and Mars illustrates the impact that solar emissions can have on Earth Environment.

An artist's impression of the magnetic fields of Venus, Earth and Mars interacting with charged particles streaming from the sun. Earth's magnetic field protects it from these atmosphere-stripping particles.

Magnetic Field Force Experiment

Earth's magnetic field, which protects the planet from harmful blasts of solar radiation, is much older than scientists had previously thought. This invisible, protective shield likely existed shortly after the planet formed; a finding that could shed light on why Earth is habitable and Mars is not. Earth's magnetic field helped make life on the planet possible. Without our magnetic field, solar winds would strip away the planet's atmosphere and oceans.

Learn about magnets --for kids (This has a nice picture of the magnetic field) but it's description of how magnets make a magnetic field isn't correct. Better find another site to describe a magnetic field)

Magnets Poster

From our Science poster range, the Magnets Poster is a great educational resource that helps improve understanding and reinforce learning.

The human Heart is now documented as the strongest generator of both electrical and magnetic fields in the body.

The Torus: The Code to the Universe

The Heart is about times stronger electrically and up times stronger magnetically then the brain.
