# Do charged particles have electric fields?

## Do charged particles have electric fields?

An electric field is a space around a charged particle where the particle exerts electric force on other charged particles. When charged particles are close enough to exert force on each other, their electric fields interact. The lines of force bend together when particles with different charges attract each other.

Can an electric field exist in empty space?

So Electric Fields are vectors (they have magnitude and direction) Electric Fields surround electric charges. Electric Fields exist in empty space (think of fields as a property of space!) It is present at any (and every) point in space.

Can electric field exist without magnetic field?

So, both the electric and magnetic fields exist without each other. So, we conclude that magnetic fields can exist without electric fields and electric fields can also exist without magnetic fields. Note: Electric and magnetic fields are both the components related to electromagnetic waves.

### What is the requirement for the existence of an electric field?

The space surrounding a charged object is affected by the presence of the charge; an electric field is established in that space. 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.

Can the electric field be negative?

An electric field can never be negative. An electric field is a force experienced by the charge divided by the magnitude of the charge. So even if the charge is negative in nature, its magnitude will also be positive and therefore, an electric field can never be negative.

What happens to a charged particle in an electric field?

In an electric field a charged particle, or charged object, experiences a force. If the forces acting on any object are unbalanced, it will cause the object to accelerate. If two objects with the same charge are brought towards each other the force produced will be repulsive, it will push them apart.

#### Does magnetic field really exist?

However, purely magnetic fields do exist. Therefore, magnetic fields are more than just relativistic electric fields. The correct statement is that electric fields and magnetic fields are both fundamental, both are real, and both are part of one unified entity: the electromagnetic field.

Can an electric field be negative?

Are electric fields always positive?

An electric field is a vector field, it has both magnitude and direction. In vector theory, the magnitude is the “size” of the vector and, like spatial sizes, is always positive.

## Can an electric field be zero?

There is no zero-field point for a pair of equal-magnitude-but-opposite-sign charges. Electric field is zero in that point because the sum of electric field vectors have same intensity and direction, but are opposite. That point is halfway between two like charges.

Which particle will not be affected by an electric field?

Alpha particles are positively charged, beta particles are negatively charged, and gamma radiation is electrically neutral . This means that alpha and beta radiation can be deflected by electric fields , but gamma radiation cannot. Remember that opposite charges attract.
