Question 1: When an external magnetic flux through a conducting loop decreases in magnitude, a current is induced in the loop that creates its own magnetic flux through the loop. How does that induced magnetic flux affect the total magnetic flux through the loop? O It does not affect the total magnetic flux. O It decreases and then increases the total magnetic flux. OIt increases the total magnetic flux. OIt increases and then decreases the total magnetic flux. O It decreases the total magnetic flux. Part (a) Some additional information, which is not included in the video, is that the SI unit of magnetic flux is the weber, denoted Wb. Using that information and the contents of the video, solve this numerical problem: A conducting loop, with a resistance of 2.0 Q2, encloses magnetic flux that is increasing at the rate of 2.0 Wb/s. The magnitude of the current induced in the loop is... (select the best choice) Part (b) 02A 04A 01/2A O1A 01/4 A Imagine a circular conducting loop glued…
An airplane flies level to the ground towardthe north pole. (a) Is the induced emf from wing tip to wing tipwhen the plane is at the equator greater than, less than, or equalto the wing-tip-to-wing-tip emf when it is at the latitude of NewYork? (b) Choose the best explanation from among the following:I. The induced emf is the same because the strength of theEarth’s magnetic field is the same at the equator and at NewYork.II. The induced emf is greater at New York because the verticalcomponent of the Earth’s magnetic field is greater there thanat the equator.III. The induced emf is less at New York because at the equator theplane is flying parallel to the magnetic field lines
(a) A 17.0 m long, thin, uniform steel beam slides south at a speed of 29.0 m/s. The length of the beam maintains an east-west orientation while sliding. The vertical component of the Earth's magnetic field at this location has a magnitude of 44.0 µT. What is the magnitude of the induced emf between the ends of the beam (in mV)? mV (b) What If? The west end of the beam impacts and sticks to a pylon, causing the beam to rotate clockwise as viewed from above. While the beam rotates, what is the magnitude of the induced emf between the ends of the beam (in mV)? (Hint: use conservation of angular momentum to find the speed of the beam after the collision.) mV
