magnetometer Definition

mag·ne·tom·eter (mag′nə tämət ər)

noun

  1. an instrument for measuring magnetic forces, esp. the earth's magnetic field
  2. an instrument for detecting the presence of magnetic materials by their influence on the local magnetic field: often used to screen for weapons at airports, etc.
