I got stuck on 8, any help is much appreciated.
Upon entering the field, a counterclockwise current flows in the loop. When leaving the field the coil experiences a magnetic force to the right. Upon leaving the field, a counterclockwise current flows in the loop. When entering the field the coil experiences a magnetic force to the left. While the loop is entirely in the field, the emf in the loop is zero. Correct, computer gets: TTFFT A conducting rod AB of length d = 0.50 m and mass 0.40 kg makes contact with the metal rails AD and BC as shown in the diagram. The apparatus is in a uniform magnetic field of flux density 520 mWb/m2 (1 Wb = 1 Tm2), perpendicular to the plane of the diagram. At the moment shown, distance AD is 2.10 m. Find the magnitude of the induced emf in the rod if it is moving to the right with a velocity of 1.10 m/s. Correct, computer gets: 2.86E-01 V Hint: Use self-consistent units! "flux density" is a fancy word for "magnetic field" (look at the units, 1 Wb/m^2 is the same as Teslas) Which of the given quantities do you need to solve this problem? Answer the following questions with regard to the diagram above. If the first is T and the rest F, enter TFFFF. In the absence of friction between rod and rail, the rod will continue to move towards the right indefinitely even if no external force is applied to keep it in motion. The induced current flows clockwise. As the rod AB moves to the right, the magnitude of the flux through the surface ABCD decreases. The magnetic field due to the INDUCED current points within the loop ABCD into the plane of the paper. The agent moving the rod to the right is doing negative work on the rod Answer: Hint: This is an application of Faraday's and Lenz's Laws.Explanation / Answer
