Planets that have strong magnetic fields also have rapid rotation and convective fluid interior zones that are also good electrical conductors. the magnetic field of venus is so weak that it has not yet been detected, which makes it at least 25,000 times weaker than earth's magnetic field. examine the venus data file in your textbook. what information here may indicate why venus is lacking a strong magnetic field?
