Hello all
I am posting on this site to ask for help with my Theory section of a experimental investigation, below is what I have done so far, my teacher has asked for the theory to be able to be understood by a average high school maths student that does not study physics. The experiment used a small electric motor that was attached to a small turbine, which was moved by running water, hence producing current.
So if possible can you be most critical, and help me with suggestions of what else to discuss, also can anyone please explain what Magnetic flux is in simple terms?
Theory
An electric motor converts electrical energy into kinetic energy. The reverse task can be accomplished by a reversing the operation of the motor. Electrical energy is the amount of work (i.e. force applied through a distance) that can be done by electricity, and kinetic energy is work needed to accelerate a body from rest to its current velocity (speed). In simple terms, this means that kinetic energy is needed to make something move, (i.e. Car wheel) while electric energy is needed to power things (i.e. Light bulb).
The way that the electric motor can transform the two energies is because of a scientific process named Electromagnetism. Electric motors make use of magnets, which are objects that have a magnetic field; a magnetic field is a region in which magnetic forces can be observed. These magnetic forces exert forces on moving charges; moving charges are everywhere. Electric motors harness this property of magnets, to induce a voltage in a conductor by changing the magnetic field near the conductor. (A conductor is a material which electricity easily flows through.) So, by running electricity through a motor a process known as electromagnetic induction takes place, and the ...
Any help would be greatly appreciated
