Magentic field is the area aronud a manget in which a mganetic force is exetred. Mvoing elcetric charegs porduce magnetic feilds. Magnetic fileds are usulaly shown by magnetic flux lines. At all times the driection of the magnetic field is shown by the diretcion of the mangetic flux lines. The strnegth of a mganet has to do with the spcaes between magnetic flux lines. The clsoer the flux lines are to each other, the strogner the magent. The furtehr apart they are, the wekaer the magnet. The flux lines can be seen by palcing iron fiilngs over a magnet. Magnetic fields give power other partciles that come in cotnact with the magnetic field.
