field strength

• Terme scientifique désignant l'intensité d'un champ vectoriel en un point donné, utilisé surtout en physique pour caractériser l'intensité d'un champ électrique, magnétique ou gravitationnel.

A scientific term referring to the magnitude of a vector field at a given point, most commonly used in physics to describe the intensity of an electric, magnetic, or gravitational field.

1. Physical field intensityC1formal

   The magnitude of a physical field (such as electric, magnetic, or gravitational) at a given point in space.

   Intensité de champ

   • The magnetic field strength was measured in teslas.
   • Engineers calculated the electric field strength near the power lines.
   • The gravitational field strength decreases with distance from the Earth.

2. Signal powerB2formal

   The power or intensity of a transmitted signal, such as radio or Wi-Fi, at a specific location.

   Intensité de champ

   • The radio field strength was too weak to receive the station clearly.
   • Wi-Fi field strength can be affected by walls and obstacles.
   • Technicians measured the field strength to optimize antenna placement.
