Cool. Is it the case that moving magnetic fields generate an electric field and it the production of this field which results in interaction between electric fields thus exerting the pressure on the protons and electrons (or any charged particles) which you write of?
Hey.
I am learning about electromagnetism and have been told that a moving charge creates a magnetic field which can then interact with an external magnetic and produces a force on the moving charge which is the basis of the motor effect etc.
I am now onto electromagnetic induction and am...
Okay. Well if that's the case then I could explain the area under the graph being equal to the energy stored if it was an electron from the negative plate moving to the positive plate when the capacitor discharges but in reality this isn't the case, is it?
So when sites talk of the energy...
Hey.
I am having major trouble understanding why the energy under the V against Q graph formed when a capacitor is charging up is equal to the energy stored in the capacitor.
I think that I do not understand this because I do not truly appreciate what the existence of a potential...
Hey. :)
I have just come onto working with vectors in pure mathematics and have no problems calculating with them. However, I do not really understand the difference between a vector and a scalar.
A scalar has magnitude only.
A vector has magnitude and direction.
Since trying to...
How do I know the charge of the particle? At this point in time I could only deduce whether a particle had positive, negative or no charge due to the direction of curvature.
Furthermore, why does it spiral? Originally the electromagnetic force accelerates the particle in one direction. Why...
Hey. :)
I am a Year 13 student and do not have to know anything about bubble chambers. However, they are mentioned in my textbook and I am interested in them.
The textbook states: "Measuring the curvature of the tracks allows the charge and mass of the particles to be deduced. The spiral...
Thank-you for taking the time out to help me.
When the electrons initially flow onto the (soon to become negative) plate I can see that electrons will be repelled from the other plate, leaving it with an overall positive charge. I had also thought that "the current is the same at all points...
Hey.
My textbook states of a capacitor that: "If one plate stores a charge +Q, then the other stores an equal and opposite charge -Q".
I understand the electrons flow onto one plate and this excess of electrons causes the plate to have an overall negative charge which then repels...
