# Can electric field and magnetic field be parallel?

Contents

Charged particle is moving along parallel electric and magnetic field. The velocity, electric and magnetic vectors are in in the same direction. Let they are aligned along x-axis. Since magnetic field and velocity vectors are parallel, there is no magnetic force.

## Can electric field be parallel?

A second characteristic of conductors at electrostatic equilibrium is that the electric field upon the surface of the conductor is directed entirely perpendicular to the surface. There cannot be a component of electric field (or electric force) that is parallel to the surface.

## What makes an electric field?

A charged object creates an electric field – an alteration of the space or field in the region that surrounds it. Other charges in that field would feel the unusual alteration of the space. Whether a charged object enters that space or not, the electric field exists.

## Can electric field be negative?

Electric field is not negative. It is a vector and thus has negative and positive directions. An electron being negatively charged experiences a force against the direction of the field.

## What is uniform electric field?

A field in which the value of the field strength is the same at all points. For example, a uniform electric field exists between two parallel charged plates. At the ends of the plates the field is non-uniform. Uniform magnetic fields may be produced by Helmholtz coils. From: uniform field in A Dictionary of Physics »

## Why do we need electric field?

Electric fields provide us with the pushing force we need to induce current flow. An electric field in a circuit is like an electron pump: a large source of negative charges that can propel electrons, which will flow through the circuit towards the positive lump of charges.

## What will happen if electric field is absence?

When an electric field is applied, each free electron acquire a drift velocity. There is a net flow of charge, which constitute current. In the absence of electric field this is impossible and hence, there is no current.
