Magneettikenttälinja
Magneettikenttälinja is a Finnish term referring to a magnetic field line. Magnetic field lines are an imaginary concept used to visualize and describe the direction and strength of a magnetic field. They are drawn such that the tangent to a line at any point indicates the direction of the magnetic field at that point, and the density of the lines represents the strength of the field, with closer lines indicating a stronger field.
These lines always form closed loops, emerging from the north pole of a magnet and entering the
Magnetic field lines are crucial in understanding phenomena such as the behavior of charged particles in magnetic
