Number Of Coils Within The Magnetic Field example essay topic
304 words
The parts of a motor are a team working together to convert electrical energy into mechanical energy. The parts, their descriptions and how they work are explained below: Armature The coil is wound onto a frame called an armature. It is usually made of ferromagnetic material (something that conducts magnetism well). The armature is usually free to rotate an axle called the armature axle. This sticks out of the motor and rotates with the coil and is used to do the work the motor is designed for.
The armature in the model is the green paint tube and the armature axle is the long white pole. Magnets The magnets provide the magnetic field in the motor. They provide a magnetic field surrounding the coil so that the moving charged particles in the coil can experience a force and make the motor work. In this example of a motor the magnets are called the stator as they do not move.
The magnets in the model are the two match boxes next to the armature. Coil The coil is the conductive wire where charged particles can move freely and experience a force due to the magnetic field. It is wounded onto the armature. Because the moving charged particles move within the coil and experience a force the coil moves in the same direction of this force. Increasing the number of coils within the magnetic field will increase the force as there will be a greater number of charged particles moving within the field.
The coil should be laminated to avoid short circuiting. In this example of a motor the coil is called the rotor as they rotate. In the model the coil is the copper wire mounted onto the armature..

I never leave reviews for products or services because I am quite particular and picky. Surprisingly enough, EssayPride has managed to satisfy all of my requirements, even though I asked for several alterations to the paper they've sent initially. My assignments are quite complicated and it is essential to possess a certain level of knowledge in order to write a decent paper. These guys have managed, so I give them four stars.

As probably any student, I was quite hesitant about asking somebody else to do my assignments at first. However, after EssayPride has sent me my first paper and I've read it, I understood that I could actually learn a lot from them. The research they've done was impressive and I understood the topic even better than after going to class and reading my textbook. I am not using this website to "cheat", I am using it as a tutoring service, they help me to understand the material better.
