I believe the earth's core creates friction as it the earth rotates and that generates the field. Not 100% on that though.

What magnet does a magnetic strip use?
To remain a magnet it has to be made out of steel as steel makes a permanent magnet.
Is iron a permanent magnet?
Yes, as it is a magnet that will remain for a long time that makes it permanent. : ) x
What is magnetization of iron?
the process of converting iron to a permanent magnet is called magnetization. As iron is a ferro magnetic material it is magnetized by applying strong magnetic field across it , this makes the alignment of all the magnetic dipoles present in iron in the same direction .Even after the external magnetic field is removed they retain their arrangement , thus it becomes a permanent magnet
What do atoms have that makes an object magnetic?
a magnet field..!
Is there a magnet in an electromagnet?
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases. Take a look at this Wikipedia page for more information: http://en.wikipedia.org/wiki/Electromagnet
Why is it unlikely that earths core is a permanent magnet?
An electromagnet only retains major magnetic properties when a current is being run through it.AnswerWhether a material makes a permanent or temporary magnet depends on the nature of the ferromagnetic material involved. For example a coil with a steel core will retain much of its magnetic flux density when the current is switched off, whereas a coil with an iron core will lose most of its magnetic flux density when the current is switched off.
How is a moving magnet used to create electricity?
makes current flow through a magnet
When a electro magnet flows through a coil of wire wrapped around a bar of iron it makes what?
a magnetic field
What a moving magnet makes?
makes current flow through a magnet
Once a current flows through the coil does it become a magnet?
ANY flowing current is surrounded by a magnetic field. The coil simply makes the magnetic field stronger.
How is magnetism is formed?
There are many ways how magnetism is cause. The main reason is due to the magnetic field of a magnet such as a bar magnet which constantly keeps creating its own magnetic field. And an electromagnet which only creates its magnetic field when it is switched on.
Why do electrons behave like tiny magnets?
a spinning electron produces a magnetic field that makes the electron behave like a tiny magnet
