Abstract In order to extend the exploration depth of the transient electromagnetic instrument, the authors have successfully developed the strong field source transient electromagnetic instrument on the basis of adsorbing ripe technology in electron industry. The instrument has such merits as transmission of large quantities of current, short cut-off time and great exploration depth. A tentative application of this instrument in a certain copper mine has proved that it can be used effectively in field work.
