| Abstract: | In order to find a design method for the size of a single-loop magnetic circuit which magnetizes a wire rope, the circuit structure is discussed. The formulae for surface leakage field distribution around the magnetized part of the ropes are derived. To choose a small magnetic leakage and to optimize magnetic length Lm are two keys for design of a small-sized electromagnetic sensor to test the broken strands in steel wire ropes. |
