Using the same approach, determine the magnitude of the magnetic field based on the emf induced at frame 1000, as the loop is exiting the field. Note: you need to measure the speed of the loop again–we suggest using a 60-frame interval centered around frame 1000.

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
