The Magnetic Force

Is most easily described by its effects—it is easy to see iron objects react or outline lines of magnetic attraction.

Page 3: Magnetism  and the Sun

Michael Faraday made reference to ’modified space’ --an area apparently affected by the magnetic force.

The present model

Suggests that (ferro) magnetism is related to the spin of valence electrons in elements such as iron, nickel and cobalt

Page 7: Magnetism  and the Sun

The Earth’s magnetic field

Is believed to be caused by movement in the (liquid) outer core due to the spin of the earth.

Page 8: Magnetism  and the Sun

The sun

Is not thought to have distinct metallic cores,

BUT…

Page 9: Magnetism  and the Sun

…does rotate at different speeds at different “latitudes”

Page 10: Magnetism  and the Sun

Matter making up the sun is in the PLASMA state--

Positive nuclei are separated from their negative

electrons

Page 11: Magnetism  and the Sun

Here’s the wild side--

When electric particles flow through a circuit—they create a magnetic field

Page 12: Magnetism  and the Sun

This was discovered

By accident, by Hans Christian Oersted in 1820

Page 13: Magnetism  and the Sun

And described mathematically

by Andre-Marie Ampere the same year

(Ampere’s Cirucuital Law)

Page 14: Magnetism  and the Sun

An electric current (I) flowing through a circuit produces a magnetic field (B)

Page 15: Magnetism  and the Sun

This means that as charged particles move throughout the sun

They create MANY magnetic fields
