YE Xiao-dong · Automation and Instrumentation · 2011
This paper analyzed the theoretical foundation of the coil of metal detector.In order to improve the sensitivity,antijamming ability and overcome the disadvantages of the complicated coil in traditional metal detector,a new type of metal detector with high sensitivity and stability based on the theory of the electromagnetic induction is presented.Then the design of structure,material is explained.Finally,the correctness and practicability of the design are verified with the experimental results.
