Edexcel Physics Practical (Unit 5)

im sure there was a very similar question...i thnk 2004 or somthin

Hall probe should be at 90 degrees to the magnetic field, no?

I couldnt think of enough points to say for that question - what were each of the marks for :O :frown:

I'm guessing he means that the probe is moved in a line parallel to the solenoid? Also, shouldn't the probe be in the centre of the solenoid, or is that what you meant?

Can any of you guys tell me what you actually wrote (in detail) for your planning section and how to use a hall probe because I only found out what it was today :eek:

,

thanks in advance :s-smilie:

about the sensor...it should be placed across the width of the Hall strip....since the power supply should be along the length

Sorry what do you mean by this?

u move the probe parallel to the solenoid making sure that the probe itself is perpendicular to the magnetic field

aww touche torchwood....i dont really remember what i have written and not stressed too much on trying to remeber them. Time to concenterate on PHY 1,2,3.

Tc all. BOL.

what does this probe look like?
:party:

a thin rectangular strip with a voltmeter across the width and a power supply along the length. the long face of the strip is to be placed perpendicular to the field....however its not really important to show the voltmeter or power connections to the strip :smile:

hi NERMIN how did you use this most strangest contraption

well nermin i have done exactly as you have written !

Yep this question is similar to one of the 2004 papers...

and the question on waves was a copy/paste job of May 2002.

Look at this website: http://www.nobelscience.org.uk/pupilpages/KS5/KS5%20Physics/physics%20exam%20papers%20PHY5%20practical.html

The 2003 wasn't on waves?!?!

ssat how did you use and write about hall probe

Also, aren't there two different PHYS 5 practicals that Edexcel make - so that schools who have too many pupils doing physics can take it on a different sitting?!? Therefore, I think I did a different paper to you lot?1!

Ugh, this looks complicated. Don't suppose you'd be kind enough to explain it to us? :wink:

well this is exactly how a hall probe works! how come ure sitting for a unit 5 exam without knowing how it exactly functions?
and yes ive just checked...the planning question was very similar to the one in may 2004...u can check the mark schemes for urself

It is made of a material that produces a voltage across its width once u place it in a magnetic field...so as long as u have indicated that the flat face of the probe is perpendicular to the magnetic fielld ure safe...even if diagrams were crappy

We do ours in two groups - mine is tomorrow, the others were today. Unfortunately there is no way in hell they will be similar :frown:

ni NERMIN, i didnt know whai a hall probe was because my teachers did not tell me
