Also, My teacher tells me that I am measuring the mass, and I need to link this to the weight. At them points I think there was just a slight power surge and on my graph I have circled those points.
The accuracy of my results is good, I used the equipment right and carefully. I set up the experiment with an iron c-core on a set of scales, and a electromagnet above, in theory, I should be able to see the weight of the c-core go down as it gets lifted off the scales.
The line got higher towards the end of the graph and the finished straight at 90 — coils. The line on my graph goes up and down, but stays straight at 30 coils.
On the 2 points that is a high number of paperclips picked up, I think they are wrong. I wrote what I could in my 1st draft I would put it on here if I knew howand then gave it to my teacher, and these are the main points that he told me work on.
I turned out that the more number of coils there are wrapped around the nail the stronger it as, therefore it picks up more paperclips. The friendliest, high quality science and math community on the planet!
Electromagnets coursework Iceman Hey there, I am studying the effect of current on the strength of an electromagnet for my GCSE assessed practial. My results are very slight at first, then they speed up the graph is not very steep, then gets steeper.
I think they should be lower down and on my Electromagnet coursework I marked where I think they should really be in an x pink cross. I varied the current using a variable resistor. To improve my investigation I think I could have obtained more results e.
My hypothesis was wrong, as was my prediction. Could this be because at first the c-core is nearer the outside of the magnetic field induced by the electromagnet, so therefore the magnetic force pulling upon it is weaker, and Electromagnet coursework it gets closer the magnetic field gets stronger, and so pulls the c-core up more?
How do I do this? Conclusion In our practical we found out that the more coils there are wrapped around the nail, the stronger the electromagnet is. Most of my results are mostly the same, 10 — 40 coils picked up paperclips in the range of 6 — 1 and 50 — picked up paperclips in the range of 2 — 7.
In a yellow pen I drew what I think the line should have looked like. Also if we were using different power packs we could have tried it out with different voltages. Everyone who loves science is here!This course will cover the fundamentals of image and video processing.
We will provide a mathematical framework to describe and analyze images and videos as two- and three-dimensional signals in the spatial, spatio-temporal, and frequency domains.

I varied the current using a variable resistor. This course is the second in a series on Electromagnetism beginning with Electromagnetism I ( or ).
It is a survey of basic electromagnetic phenomena: electrostatics; magnetostatics; electromagnetic properties of matter; time-dependent electromagnetic fields; Maxwell's equations; electromagnetic waves; emission.
Electromagnetic Field Theory BENGT LUNDBORG who created, developed and taught the earlier, two-credit course Electromagnetic Radiation at our faculty. Intended primarily as a textbook for physics students at the advanced undergradu-ate or beginning graduate level, it is hoped that the present book may be useful for.
