Below is a list of characteristics for electric and magnetic fields. put an "e" in front of the statement if it applies only to electric fields. put an "m" in front of the statement if it applies only to magnetic fields. and put a "b" in front of the statement if it applies to both types of fields. always form closed loops point away from positive charges the closer together the lines are, the stronger the field is. end on south poles point in the direction a positive charge would move never cross field decreases as you move away from what's causing it
