# E-field of a moving charge at constant velocity

• STosh9
In summary, the "E-field of a moving charge at constant velocity" is the electric field produced by a charged particle moving at a constant speed, responsible for the movement and interaction of other charges. The strength of the E-field is directly proportional to the velocity of the charge and is always perpendicular to its direction. When the charge changes direction, the E-field also changes direction. The E-field of a moving charge is stronger and more complex than that of a stationary charge.

But I can't figure out what gamma(u) is.
That's the usual Lorentz factor of special relativity. See: Lorentz factor

Thanks. So if the charge is moving slow compared to c, then the field resembles that of a stationary charge.

## What is the "E-field of a moving charge at constant velocity"?

The "E-field of a moving charge at constant velocity" refers to the electric field that is produced by a charged particle as it moves at a constant velocity. This field is responsible for the movement and interaction of other charged particles within its vicinity.

## How is the E-field affected by the velocity of the charge?

The strength of the E-field is directly proportional to the velocity of the charge. As the charge moves faster, the E-field becomes stronger, and as it slows down, the E-field weakens.

## What is the direction of the E-field in relation to the velocity of the charge?

The direction of the E-field is always perpendicular to the velocity of the charge. This means that if the charge is moving in a straight line, the E-field will be in a circular pattern around the charge.

## How does the E-field change when the charge changes direction?

When the charge changes direction, the E-field also changes direction accordingly. This is because the E-field is always perpendicular to the velocity of the charge.

## How does the E-field of a moving charge compare to a stationary charge?

The E-field of a moving charge is stronger and more complex compared to that of a stationary charge. This is because the moving charge creates a changing electric field that affects the surrounding space, while a stationary charge only creates a static electric field.
