What layer of earth creates earth magnetic field?
The Earth's magnetic field is the result of electric currents in the liquid metal outer core.The outer core of the Earth is over 2,000 km thick. It sits above the solid inner core and is composed of highly conducting liquid iron and nickel. Above the outer core is the Earth's mantle.The geodynamo is the mechanism thought to be responsible for the electric current in the core and the generation of the Earth's magnetic field through the convection of conducting fluids in the Earth's core. Other planets with a molten metal core can also have a magnetic field.See related links.
What type of microscope uses a magnetic field magnifies up to one million times?
nothing because i dont know
Which has a stronger magnetic field a solenoid or a electromagnet?
A solenoid is an electromagnet An electromagnet is a solenoid with an iron core
Is static electricity in magnets?
Static electricity uses positive and negative charges contained within a non-conductive material to attract or repel another object with off balanced charges. Magnetism uses the polarity of atoms to attract or repel another object that can potentially be a magnet.
How can a person's magnetic field interfere with electrical appliances?
It is possible to create a Theremin-like device, (http://www.answers.com/topic/theremin?cat=entertainment) but your magnetic field (actually, you are dealing with electric fields) will not do anything to most electronic appliances (except for very sensative things, but you probably dont have those in your house)

Does the area of magnet effect the magnetic field?
i really dont know
Are the planets with rings inner or outer planets?
Only the four outer planets have rings. The four inner planets (Mercury, Venus, Earth and Mars) dont have rings.
In what earth layer does out magnetic field originate?
Magnetic declination changes over time because themagnetic poles move slowly, between 1580 and 1820, for example the direction of magnetic north in London changed by 35 degrees Written by Londyn reid 13 yrs old
How many planets away is Jupiter from earth?
i dont know you guys find the answer. lazy retards!!!!
What is one of the problems that solar storms cause on earth?
nothing at the moment, we are protected by a force field if you like wich surrounds the earth meeting at the polls crated by the core of the earth spinning, this magnetic field fights off the solar flares and pushes them past us, some of the energy matter can come down to polls and when it collides with the atmosphere it creates a light show, also known as the northern/southern lights, but for know i dont think it worrys us
Is the earths gravity the same as the magnetic field if not what is the difference in effects?
i dont know its aload of bumf go away :p
What type of microscope uses a magnetic field magnifies up to one million times?
nothing because i dont know
What planet has a nickel-iron core and spins in a 24-hour cycle?
Earth.
Any other planets that orbit the Sun have Seasons like Earth?
yes there are seasons like earth on other planets. Except, they all dont have the same tempuratures or the same period one or more season lasts.
How is the earth's surface different from the other Inner planets' surface?
i dont know i want to find this out too hehe
Is ther any life on any planet?
not that we know of. but the 8 planets we have, all of them dont except earth has life.
