If it is sticking up above the commutating bars one tiny iota the brushes are launched off of the mica and land somewhere later on the bars. Much heap big sparky. So shops often have a jig with a dremel tool like apparatus, that lets you run a straight pass down the mica strips. Lowers the mica, squares up the C.

The friendliest, high quality science and math community on the planet! Everyone who loves science is here! Electromagnets coursework Iceman Hey there, I am studying the effect of current on the strength of an electromagnet for my GCSE assessed practial. 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.

I varied the current using a variable resistor. My results are very slight at first, then they speed up the graph is not very steep, then gets steeper. 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 as it gets closer the magnetic field gets stronger, and so pulls the c-core up more?

Also, My teacher tells me that I am measuring the mass, and I need to link this to the weight. How do I do this? I am very unclear about the two of the above, Any help very much appreciated. 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.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, .

Science Coursework: How does the number of coils on an electromagnet affect its strength? Aim: To establish whether a variation in the number of coils will affect an electromagnet's strength/5(1).

electromagnet can be as strong as possible since more windings can permit greater magnetic strength [3]. A battery was then taped parallel to the nail shaft and the ends of the wound wire. Course Description. Electromagnetic Theory covers the basic principles of electromagnetism: experimental basis, electrostatics, magnetic fields of steady currents, motional e.m.f.

and electromagnetic induction, Maxwell's equations, propagation and radiation of electromagnetic waves, electric and magnetic properties of matter, and . 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.


CBSE Class 7 Science - Electric Current & Its Effects. Worksheets have become an integral part of the education system.

Worksheets are very critical for every student to practice his/ her concepts.
