Apparatus used for interconnection-cable induced magnetic field test

The utility model discloses an apparatus used for an interconnection-cable induced magnetic field test. The apparatus comprises a 100W audio power amplifier, a signal generator, a pure resistor, multi-turn lead coils and an oscilloscope. An output terminal of the signal generator is connected to an input terminal of the 100W audio power amplifier. An output terminal of the audio power amplifier is connected to the pure resistor. The other end of the pure resistor is connected to the multi-turn lead coils. The other end of the multi-turn lead coils is connected to the audio power amplifier so as to form a loop. The oscilloscope and the pure resistor are connected in parallel so as to monitor a voltage on the pure resistor. Each turn of the lead coil is in a rectangle shape. An interconnection cable of tested equipment and a long edge of the rectangle multi-turn lead coils are laid in parallel. The apparatus is convenient to implement. Operation is simple, cost is low and an effect is good.
