In an electric motor, at the moment that the half-turn of the rotor (central electromagnet) completes, the field of this electromagnet
it flips
if you think about it, if you put two positive or two negative sides of a magnet together what happens? one flips because they aren't attracting

What is transferred energy?
I assume you mean what it is converted to. It can be converted to many different types of energy; that's one of the things that makes electrical energy so useful. (The other useful feature is that it is relatively easy to transport.) For example, a heating device can convert electrical energy to heat; a speaker converts it to sound; a television set or a computer monitor converts it to light; etc.
What type of simple machine is a lightbulb?
It is an electrical device that transmits energy to help us see more clearly. It contains a filament which is heated to incandescence by an electric current.
Kinetic energy is based on its what?
Kinetic energy is the energy of motion. It's that simple.
What are 3 simple examples of mechanical enrgy?
kinetic energy, potential energy, light energy.
What is an example of electrical energy being transformed into light energy?
An example would be a simple light bulb. As the electrons pass through the filament (wire) in the bulb the high resistance of the filament causes very small but fast vibrations which become light (and heat) hope it helped :)
How do you construct a device to convert sound energy into electrical energy?
A simple method is already available and it's called a speaker-you can also use it as a microphone.
What is a simple definition of electrical energy?
The energy in an electrical current, or stored temporarily in capacitors or inductances.
What does a simple circuit consists of?
Electrical energy
What do magnet have to do with simple motors?
Motors convert electrical energy to mechanical energy through moving electric conductors through a magnetic field. Magnets can be permanent magnets or electromagnets.
What is the kind of energy that leaves convert the suns light energy into?
simple: chemical energy: )
How can you construct a device that can convert electrical energy to heat energy?
This seems like a question from an electrical course, and is probably best answered by your course materials. It's your test question, not ours, and there won't always be someone to ask for the answer. Earn your diploma. However, a simple resistive load will dissipate heat, thus changing electrical energy to heat energy.
Explain how a simple motor functions?
it converts electrical energy into mechanical energy
Can you convert mechanical energy to heat energy?
Absolutely a simple example is the engine.
What type of energy is gathered by solar panels and converted into electrical energy?
Very simple; solar energy!
Can you give me an example of a simple sentence using the word electromagnet?
There is an electromagnet in that crane
How can electrical energy turn into heat energy?
This is quite simple with a resistor. That device will turn electricity to heat.
Energy transformations in a loudspeaker?
A loudspeaker is a transducer which converts electrical energy into sound. [Most simple moving coil loudspeakers will also function in reverse, as a microphone turning sound energy into electrical energy.]
