Transcribed Image Text:The figure below shows a flexible loop of metal wire with a radius of 15.0 cm. It lies in a magnetic field pointing into the page with a magnitude of 0.140 T. A physicist grabs the loop at
points A and B and rapidly pulls in opposite directions until the loop folds up, such that its area becomes zero. The change in area occurs in a span of 0.190 s.

- The figure below shows a flexible loop of metal wire with a radius of 10.0 cm. It lies in a magnetic field pointing into the page with a magnitude of 0.130 T. An engineer grabs the loop at points A and B and rapidly pulls in opposite directions until the loop folds up, such that its area becomes zero. The change in area occurs in a span of 0.250 s. A В What is the average induced emf (in mV) in the loop over this time span? 16 What is the initial magnetic flux through the loop? If the loop's area goes to zero, what is the final flux? How is the change in flux and change in time related to the induced emf? Be careful with unit conversions. mVarrow_forwardCan you please answer the question!! THE ANSWERS ARE NOT 18.4 W OR 39.1 W!!!!arrow_forwardA single ring is moving through a magnetic field that varies in strength. The ring has a radius of 9.5 cm and it is moving at a velocity of 30 S The ring is oriented so that the magnetic field passes directly through the ring. It moves such that the magnitude of the magnetic field through the ring changes from 0.84 T to 2.25 T in 0.21 s. What is the magnitude of the induced emf in the ring? emf = V You measure the induced current in the ring as 1.54 A. What is the resistance of the ring? R = Ω What changes could you make in the system to increase the induced emf in the ring? Increase the number of loops in the ring Increase the velocity of the ring through the magnetic field Decrease the velocity of the ring through the magnetic field Decrease the area of the ring Increase the area of the ring Decrease the number of loops in the ring O O O O Oarrow_forward
