Prototype #4

Prototype #4 was very similar to #3 in structure and theory the only real change being the number of prongs coming out of the axel. I added to more prongs to my axel to help pick up the magnetic field easier. The prongs also added length of the the coil, and due to our equation F= IlB, the length of the wire would increase the force of my axel.







The issue found was the way the force was being applied. Due to the Right Hand Rule, and the the way force works with a magnetic field, the force was not going the way I wanted. It was going into the page rather than to the right and I needed to fix that in my next prototype.

Physics Motor Entry #1

Preview Mode To Be Used On Every Slide  The Creation of a Electro-Magnetic Motor The creation of my motor showed many stages of development. I believe these stages to reflect the amount of knowledge I had on the practicalities of creating a motor. But before getting into the electric motor, we must learn its background the first rotating device driven by electromagnetism (electric motor) was constructed by the Englishman Peter Barlow in 1822 (Barlow's Wheel) . The first practical application of an electric motor was created in 1835 by two Dutchmen named Sibrandus Stratingh and Christopher Becker, near the birth of electricity. The first known application of the motor, was for a small model car in 1837. The electric motor today, is used in many home products. Cameras for there shudders, fans to create motion and new, climate saving cars use electric motors to create motion. the creation of electric motors seems so complex and deep so the question stands, is it possible to create a

Prototype #4.5

<-- recreation (initial image not found)  Prototype 4.5 was the near to the final creation. I created it with the right hand rule in mind. The direction of the current would dictate the direction the axel would move in. This prototype was created to be sturdy and hold the wire in place while stimulating the force needed to create movement This also managed to update my risk assesment as the current it created managed to melt the wire i was using and fuse it to the glove I was wearing to protect myself from the super glue and heat. Prototype #4 was not a success due to my finding that the boxes coils went against the magnetic field, meaning i had to rethink my design once again. Results : Heaviy magnetic force No spin

Prototype #3

 After a long period of stagnation I came back to the motor project with fresh eyes. A new out look on how the motor should be made. I wanted a sturdier frame so I didn't have do deal with movement that came from minuscule lapses in movement that would completely destroy Mark 1 and Mark 2. Mark 3 of the motors was a complete over haul of my initial plan for the motor this was due to my study on theoretical ideals of the motor, particularly the equation F = I*l*B. Increasing the length of my coils would inevitably increase the force, I also decided to change my magnets to stronger ones that would create a stronger magnetic field, and I changed the power source I was using and the amount of coils to increase the amount of current. All of these changes were done to create a stronger force The new motor was a new prong design. The 2 prongs were connected to the axel in order for the force to be forced side ways with the magnetic field.  At the time i believed the issue to be that the
