Which of the following laws may be used to find the direction of the current induced in a loop close to a moving magnet? a) kirchhoff's law b) faraday's law c) joule's law d) lenz's law e) ohm's law

According to Lenz's law, the induced current produces a magnetic filed that opposes the changing magnetic field producing it. For example if the magnet is getting closer to the loop, the current produced in the loop must be such that its magnetic field pushes back the approaching magnet. If the magnet is moving away from the loop, the magnetic field due to the induced current must attract the magnet.

“other instruments such as gravimeters and magnetometers are also used in the search for petroleum. extracting crude oil normally starts with drilling wells into an underground reservoir. when an oil well has been tapped, a geologist (known on the rig as the "mudlogger") will note its presence. “ this is what i found on google i hope it

This did i unseated, sorry
