How do scientist know that magnetic field originate from north always?

There are two kinds of magnetic poles. It is just a matter of convention that we *define* one of the north. Then we *define* the direction of the magnetic field to be the direction of force experienced by a test north pole. Magnetic field lines and their directions don't really exist, they can only be observed indirectly. It follows from our definition that they must originate in the north poles.

What is a property of a magnetic field?
One property of a magnetic field is that its divergence is zero. That means that a magnetic field line is always a loop and that the net magnetic field coming out of or going in to an enclosed surface is always zero. The result of this is that there are no magnetic monopoles, at least none discovered. Theories, however, do abound.
Is earth magnetic field bigger then Venus?
The Earth's magnetic field and the plant Venus is the same size. Scientist say that Earth and Venus are twin plants.
What must a magnet always have?
A magnetic field.
What is the classical explanation of a dc electric current in a metallic wave?
A changing magnetic field always produces an electric field, and conversely, a changing electric field always produces a magnetic field. This interaction of electric and magnetic forces gives rise to a condition in space known as an electromagnetic field.
Are the magnetic lines force of a bar magnets strongest at the end of the magnet or in the middle?
That is where the field lines originate and therefore where they are thickest. The thicker the field lines, the stronger the field. To see the magnetic field lines, cover your magnet with a piece of paper and spread metal fillings over it.
What pole do magnetic field originate?
north and south pole
What do scientist produces earths magnetic field?
Its molten iron core.

How is the earths magnetic field used for navigation?
Compasses use the magnetic field to navigate always pointing North.
Why are magnetic field lines closed and continues curves?
Among the field lines generated by a circle current, the one which passes the center is not closed. --JF Hu
British scientist who discovered that a changing magnetic field can produce an electric current?
faraday
What do scientist not know about earths magnetic field?
When the north pole becomes the south pole.
