Definition
"Field strength" refers to the magnitude or intensity of a force field at a particular point in space. This could be a magnetic field, electric field, or gravitational field. It indicates how strongly the field influences objects within its range. Think of it as the force felt when you're close to a magnet—the closer you are, the stronger the pull. Field strength is a measurable quantity, often expressed in units like Tesla (for magnetic fields) or Newtons per Coulomb (for electric fields). It's a crucial concept in physics and engineering.
