Due to the permanent magnetiron embedded in electromagnetic ultrasonic transducer（ EMAT）

it is extremely difficult to move when detecting the ferromagnetic material

it is inconvenient especially in high temperature environment. Therefore

by establishing the finite element model for EMAT embedded in pulsed electromagnet（ PE-EMAT）

influence of process parameters of pulsed electromagnet on the magnetic field and the induced eddy current intensity are analyzed. At the same time

in order to make PE-EMAT adapt to hightemperature environment

a heat transfer model for the internal fluid is established and the interaction between inner flow field and the temperature field is studied to construct the optimal water circulation cooling system. Based on the above optimization

a built-in non-destructive testing platform of PE-EMAT suitable for high temperature is set up and verified experimentally. The experimental results show that the optimized pulsed electromagnet iron can replace the permanent magnet

and the PE-EMAT non-destructive testing system can accurately detect the material internal defects at high temperature

and the detection performance is close to EMAT.
