WEEK FOUR

WEEK 4:

The vibration of the magnet in the magnetic field was not significantly reduced after neither the program modification nor upgrading the stand from a shaky sticks-cardboard combination to a frame made of wood plates. Worse still, one of the pin of the Hall effect sensor was broken after being smashed many times by the attracted magnet. We ordered another five new Hall effect sensors for our project. Meanwhile, a more powerful electromagnet of 10kg lift capability was ordered as well. The weak lift force might be a potential to the instability of magnet levitation.

WEEK 3: During the week we have successfully extended the time of magnet levitation to three seconds. However, the magnet would then start vibrating till it fell or being attracted to the electromagnet. A lot of factors that could affect the stability of the magnet floating. The program used for Arduino control was the top 1 on our trouble shooting list. We also considered to build a stronger stand by wooden material for the electromagnet and Hall effect sensor installation. The professor was giving suggestions to our group members

In this blog, the year 2 project can be found, which is a magnetic levitation system. Group member:  Haonan.Xu, Ruoquan.Wang, Junhao.Zhang, Jian.Liu, Taikun.Wu Process of week 1: Firstly, the team searched the relevant principles on the Internet. After the discussion, the basic circuit design diagram had been designed. The five team members were divided into three groups in the laboratory. The first group took charge of connecting the circuits. The second group designed and built a frame structure that supported the electromagnet to perform a magnetic levitation test. The third group was responsible for writing the code to control the magnetism of the electromagnet and the operation of the Hall element.   Before the end of the experiment, the work of each group was basically completed, and the connection and debugging work would start in the second week.

Process of week 2: The prototype of the magnetic levitation system had been completed. The team members assisted each other and connected and reinforced the four main sections, which were the circuit board, structural frame, electromagnet, and Hall element, with electric soldering iron and hot melt adhesive. Then, after inputting the code into the control board, the electromagnet generated a magnetic force towards the small magnet below. However, the magnetic force at that time was unstable and could not be balanced with the gravity of the small magnet placed underneath. In order to achieve balance, it was necessary to adjust by continuously inputting different values ​​on the computer. This process took the team about approximately, and finally the long magnet below the electromagnet reached an equilibrium of 3 to 4 seconds. At the same time, the team found that the brackets currently used produced jitter during the magnetic levitation, which would increase the imbalance of ...
