a.c. current in the conductor creates a magnetic field outside the cable. This alternating B -field generates, according to the Maxwell laws, an alternating electric field 262 10 Environmental Issues with very tiny amplitude within the ran...
AI summary The text explains that alternating current in conductors generates magnetic and electric fields, with the latter being extremely weak (μV/m) compared to everyday sources. Elasmobranch fish can detect these fields, potentially affecting their behavior. The magnetic field strength is calculated using the Biot-Savart law, highlighting technical aspects of electromagnetic impacts.
