摘要：
The magnetic field radiated from a small loop antenna is used for calibration of field strength meters. When conductive objects are in close proximity to the antenna, the magnetic field is affected by them. The effects of a conductive square plate ( less than 2 multiplied by 2 m**2, and those of an upright human body on the magnetic field were studied at frequencies up to 50 MHz. The transmitting and receiving loop antennas were arranged coaxially, the spacing between them ranging from 0. 25 to 0. 75 m. The conductive objects were moved parallel to, and then normal to the loop axis. The relationships between the limit of the errors and the distance from the object to the antenna are presented in tables for each object/position combination.
