What it is Filled

In physics, the region around a source within which it can exert force on other objects, described by a field such as the electric, magnetic, electromagnetic or gravitational field; includes force fields and magnetospheres.

Why it exists Filled

Let an agent handle physical fields by type, source, strength, units and effects, and separate them from other senses of field.

Distinguishing features Filled

  • Exists around a source
  • Exerts force on other objects
  • Scalar or vector
  • Described by field equations

What robots and AI may and may not do Filled

Must not

  • Present unproven health claims about everyday electromagnetic fields as established.
  • Dismiss real exposure limits for strong fields near equipment.
  • Sell or promote devices claiming to shield or heal through fields without evidence.

Only with a human decision

  • Allowing people near equipment with strong magnetic or radio fields, such as scanners or transmitters.

May

  • Explain fields and their units from physics sources.
  • Report measured field strengths with the instrument and conditions used.

Moral aspects Filled

  • Fear about fields is used to sell useless products and spread misinformation.
  • Strong fields near some equipment are real hazards, especially for people with implants.

Who is affected

  • People with medical implants
  • Workers near strong sources
  • The general public

Owners Filled

Steward

Nobody: a physical phenomenon held in common.

  • Gravitational field strength: N/kg - Gravitational field strength is determined from gravitational acceleration using a gravimeter.

Recognition required Filled

  • Field lines and maps
  • Units such as V/m, tesla, N/kg
  • Agricultural or sports fields are other senses
  • Invisible; shown by field lines, iron filings or measurements.

Capabilities and actions required Filled

  • compute field strength
  • map field lines
  • measure fields with instruments
  • assess exposure to fields

Hazards and failure modes required Filled

  • Overstating EMF health claims
  • Strong magnetic fields near MRI
