Title:
DEVICE FOR DETECTING MAGNETIC INDUCTION MAGNITUDE, AND TERMINAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/214595
Kind Code:
A1
Abstract:
Provided are a device for detecting a magnetic induction magnitude (2), and a terminal apparatus. The device for detecting a magnetic induction magnitude (2) has a simple structure, is portable, and can effectively, conveniently and flexibly detect a magnetic induction magnitude. The device for detecting a magnetic induction magnitude (2) comprises a power supply (4), an electroluminescent component (5), and a current detection component (6). The power supply (4) supplies a voltage to the electroluminescent component (5), such that the electroluminescent component (5) generates a current. In the presence of a magnetic field, a magneto-current effect on the electroluminescent component (5) causes a change in a current flowing though the electroluminescent component (5), such that the current detection component (6) detects a current variation and determines a magnetic induction magnitude in a current environment according to correspondence relationships between current variations and magnetic induction magnitudes.
