Electricity generator lab

There was a change in my original plan. On tuesday in class, it only took me about 10 minutes to finish the electromagnetic lab, and since my partner was not in class that day, I decided to go ahead and start the electricity generator lab. Then, on wednesday, instead of doing the second practice problem, I finished up the lab. 

From the electricity generator lab, I learnt that when the speed of the bar magnet is increased, then it results in more voltage. From the data I could see that when the magnet was moving at 10 RPM, then there was barely any voltage at all. However, as it went to 30 RPM the voltameter started moving faster, and finally at 70 RPM, it was moving very fast. This is due to the fact that when the magnet is moving faster, it results in the electrons also moving back and forth faster. This results in the voltameter moving back and forth, which shows us more voltage. 

Electromagnets Lab

What I was looking to find out was, how does the battery voltage affect the magnetic field of a magnet? From doing this lab, I learnt that the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. In addition, the poles of an electromagnet can even be reversed by reversing the flow of electricity. The magnetic strength is the same for each absolute value, even if the x and y axis poles are different.

Time Management

I think that my problem is the fact that I don't go exactly as my plan wants me to. I am good at making plans for my self. However, I have a hard time following them for some reason. Sometimes its not my fault. For example, in class I couldn't do investigation 6 because it wasn't ready so I did 7 instead. However, when it comes to managing my time at home. I should be doing much better, and I know I can. Instead of doing investigation 6, my partner Ploy and I started the simulation on magnetism and electricity. We did a lab on this and our question was, "How does the voltage effect the magnetic field of a magnet?" We haven't tested it yet, but we assumed that if the voltage is more, then the magnetic field of a magnet will be stronger. Due to the fact that it will have more power to expand it’s magnetic field.

Ferromagnetic Materials

In investigation 4, i worked with iron fillings. I magnetised and demagnetised iron fillings inside of a straw. While the straw was magnetised, we put it next to some more iron fillings. We saw that when the iron fillings lined up in one direction, it meant that the straw was magnetic. However, When they were scrambled, it wasn't magnetic. In addition, we saw that when something is magnetised and you place a compass near it, then the needle of the compass will always point to the magnetic object. However, I'm still a little confused as to how magnetising and demagnetising occur. So, I will try to get the answer to that question.

Differences between electrostatic and magnetic interactions

While doing investigation 2, I discovered some differences between electrostatic effects and magnetic effects. Firstly, I found out that magnetic interactions can be stronger. For example, in one of the tests we did, I saw that a magnetic interaction can still take place even with a paper acting as a barrier. However, electrostatic interactions don't take place if something is blocking the way. In addition, I also saw that water doesn't have an effect on magnetic attractions. However, inside the water, the electrostatic interactions did not take place. This further adds to the fact that magnetic attractions are stronger.
