MRSO questions well answered 2024/2025

MRSOFaraday's Law of Induction - correct answer Describes currents produced by changing magnetic fields E=dt/dΦ Faraday's First Law - correct answer A change in magnetic field while in the presence of a coil of wire will produce a voltage Faraday's Second law - correct answer The amount of induction is equal to the rate of changing flux and the number of wire coils When we ___________________ the number of coils in an electrically conductive object, we decrease the amount of voltages produced in this material. - correct answer Decrease When we _______________the magnetic flux strength in our changing magnetic field, we will increase the amount of voltages produced in this material. - correct answer Increase As we the speed of the changing magnetic field, we will ___________ voltages in our electrically conductive material. - correct answer Increase Magnetophosphenes - correct answer When moving a patient through magnetic flux, voltages can be produced in the optic nerve demonstrating seeing flashing lights PNS - correct answer Peripheral Nerve stimulation: The induction of current in human tissue during MRI. This can cause muscle twitching or discomfort Eddy currents - correct answer The electrical currents generated in a conductor by changing magnetic fields or movement of the conductor within the magnetic field Lenz's Law - correct answer The induced current flows in a direction so as to set up a magnetic field to oppose the change in magnetic flux Φ - correct answer Flux symbol Ohm's Law equation - correct answer V=IR As we increase the current in a conductor, we ____________ resistance. - correct answer increase As voltage decreases in a conductor, we __________________________
