Answer #1

Here

when a magnet is moving near a solenoid , the magnetic flux through the solenoid changes ,according to Faraday's law

due to this change in magnetic flux , an electric field is induced which results in development of voltage across a solenoid.

for the speed of magnet , as the rate of change of flux will increase if the speed of magnet is increasing , hence , the induced emf will also increase

turning the magnet upside down does not change the magnitude of flux through the solenoid , hence , it does not affect the magnitude of voltage , just changes the polarity of the voltage

Finding the Spring Constant We can describe an oscillating mass in terms of its position, velocity, and acceleration as a function of time. We can also describe the system from an energy perspective. In this experiment, you will measure the position and velocity as a function of time for an oscillating mass and spring system, and from those data, plot the kinetic and potential energies of the system. Energy is present in three forms for the mass and spring system....
