Calculate the initial strength of the magnetic field.(Give your answer in tesla but don't include the units.)
You are going to design a generator using the principles learned in Electromagnetism. Some typical situations are given. Use your imagination to go beyond the calculations and explain how you will design your own generator. Figure is attach Figure below shows a simple alternator, a device that generates an emf.

An instrument based on induced emf has been used to measure projectile speeds up to 6 km/s. A small magnet is imbedded in the projectile as shown. The projectile passes through two coils separated by a distance d. As the projectile passes through each coil, a pulse of emf is induced in the coil. The time interval between pulses can be measured accurately with an oscilloscope, and thus the speed can be determined. (a) Sketch a graph of ΔV versus t for the arrangement shown. Consider a current that flows counterclockwise as viewed from the starting point of the projectile as positive. On your graph, indicate which pulse is from coil 1 and which is from coil 2.
