I have to do a question and I am stuck on it, can anyone help me with it?
You are trying to do Thomsons e/m experiment and you have a 0 to 250V variable high voltage supply and a wide gap electromagnet with field of 0.5 T in the gap
a) draw a diagram of the apparatus showing the placcement of the internatl components and any needed dimensions, which will be given to a glass blowing vacuum technology section for constrution of the unit
b) You discover that your variable supply can only go to 200 and not 250.
Your supervisor said he will buy a cheap fixed version rather than a new variable. You realize that using both supples will allow you to solve the problem. Explain how using the two supplies can get over the problem
c) Calculate the output voltage required from this supply for your purpose
If anyone can help with any parts i wood be greatful
I have tried to draw the apparatus but i can't find any thing on how to find out the dimensions of an electromagnet of 250V and 0.5T. If you give me the formula used to figure this out i wood be greatful
For part B i would think if you put the two power supplies in series you would get the needed output, but i don't no if that would work in reality or only I am my world
