Claim:
1. A method, comprising inducing a first broadband magnetic field at a first transmitter position of a transmitter coupled to a tool in a well bore drilled through a formation; detecting at a first receiver position of a first receiver coupled to the tool in the well bore a first formation magnetic field (V detecting at a second receiver position of a second receiver coupled to the tool in the well bore a second formation magnetic field (V inducing a second broadband magnetic field at a second transmitter position in the well bore; detecting at the first receiver position in the well bore a third formation magnetic field (V detecting at the second receiver position in the well bore a fourth formation magnetic field (V computing a formation property using a function of V using the formation property to plan an activity related to the formation; and executing the plan.
