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 else can I help you with?
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.
Describe magnetic line of induction?
Magnetic lines of induction, also known as magnetic field lines, are imaginary lines used to represent the direction and strength of a magnetic field. They always form closed loops, flowing from the north pole of a magnet to the south pole. The density of magnetic field lines indicates the strength of the magnetic field in a particular region.
What can you conclude about the orientation of the beam relative to the magnetic field when a beam of electrons passes through a magnetic field without being deflected?
If a beam of electrons passes through a magnetic field without being deflected, then the orientation of the beam is perpendicular to the magnetic field lines. This is because the force acting on a charged particle in a magnetic field is always perpendicular to both the magnetic field and the velocity of the particle, causing the electrons to move in a circular path perpendicular to the field lines.
Which is true of magnetic field lines but not electric firld lines apex?
Magnetic field lines always form closed loops, while electric field lines begin and end on charges. Additionally, magnetic field lines do not originate from monopoles, while electric field lines can begin and end on electric charges.
What pole do magnetic field originate?
Magnetic fields originate from the north and south poles of a magnet or a magnetic material. These poles generate magnetic flux lines that flow from the north pole to the south pole, creating a magnetic field around the magnet.
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.
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.
British scientist who discovered that a changing magnetic field produces an electric current?
faraday
What are One of the differences between electric and magnetic fields is that electric fields lines always form closed loops?
One key difference between electric and magnetic fields is that electric field lines originate from positive charges and end on negative charges, forming closed loops; whereas, magnetic field lines always form closed loops, never having a starting or ending point.
Why are magnetic field lines closed and continues curves?
Magnetic field lines are closed and continuous curves because they represent the direction of the force experienced by a magnetic north pole placed in that field. The lines form closed loops because magnetic field lines never start or end; they always form complete loops that return to their origin. This continuous nature of magnetic field lines reflects the continuous nature of magnetic fields in space.
