# Your question: Do electric fields combine?

## Can magnetic fields merge?

Magnetic field line merging can be defined as “the process where- by plasma flows across a surface that separates regions containing topologically different magnetic field lines” (Vasyliunas, 1975).

## Why can’t electric field lines intersect?

If the lines cross each other at a given location, then there must be two distinctly different values of electric field with their own individual direction at that given location. … Consequently, the lines representing the field cannot cross each other at any given location in space.

## What does it mean when the electric field lines are close together?

A line tangent to a field line indicates the direction of the electric field at that point. Where the field lines are close together, the electric field is stronger than where they are farther apart.

## Is magnetic reconnection real?

Magnetic reconnection is a process that occurs nearly anywhere there’s plasma. The fourth state of matter, plasma, is gas made up of unbound ions and electrons. As plasma makes up the stars and 99 percent of the visible universe, magnetic reconnection is quite common. However, it is poorly understood.

## What is the value of 1 Tesla?

One tesla is equivalent to: 10,000 (or 104) G (Gauss), used in the CGS system. Thus, 10 kG = 1 T (tesla), and 1 G = 104 T = 100 μT (microtesla).

## Can electric field lines intersect in free space?

Question: Can electric field lines intersect in free space? Answer a. Yes, but only at the centroid of an equilateral triangle with like charges at each corner.

## Why electric field lines do not pass through conductor?

The net electric field inside a conductor is zero. Therefore, the electric field lines do not pass through a conductor.
