1685 - How do electric field lines represent the magnitude and direction of electric fields?

Imagine you have a map that shows you the path of a compass needle near a magnet. Electric field lines work in a similar way, but for electric fields around charged objects.

Here's how electric field lines represent the magnitude (strength) and direction of electric fields:

1. Direction: Electric field lines always point in the direction that a positive charge would move if it were placed in the field. This means they always point away from a positive charge and towards a negative charge.
2. Magnitude: The closeness of the electric field lines represents the strength of the electric field. If the lines are close together, the field is strong. If they're far apart, the field is weak.

So, by looking at the electric field lines, you can see both the direction and strength of the electric field around a charged object.
