Two technicians are discussing electromagnetic induction. Technician A says that the induced voltage can be increased if the spe
ed is increased between the conductor and the magnetic lines of force. Technician B says that the induced voltage can be increased by increasing the strength of the magnetic field. Which technician is correct ? A. Technician A only B. Technician B only C. Both D. none of them
There are three ways to increase the induced voltage in electromagnetic induction:
1) increase the speed at which the conductor moves through the magnetic field. This means that the lines of flux are cut more quickly and more emf is induced.
2) use stronger magnets which provides a stronger magnetic field and more densely packed lines of flux.
Food insecurity, because you are only lacking safe and nutritious food. It would be famine if you had no food whatsoever, and it would be a food shortage if you were lacking a small amount of ALL food
Scientists conduct experiments or observations to gather evidence that either support or disprove a given hypothesis. Hence, all the scientific explanations are based on this body of observations.
