at 5:42 - What is Electromotive Force? Why does it make electrons move (make electric current) in one direction?

In that video, the electrons (-) are moving to the top. It's because of the direction of the magnetic field. It could have been either way.mo0nfang said:Electromagnetic Induction @1:40 <--- Why protons group themselves at the top and electrons at the bottom?
Again, it is the Lorentz force, of which you are well aware.mo0nfang said:Electromagnetic Induction @1:40 <--- Why protons group themselves at the top and electrons at the bottom?
How concentrated energy is in an electric field. Lorentz force moves charged particles to positions of higher potential energy.mo0nfang said:What is Electromotive Force?
Electromotive force, also known as voltage, is the potential difference between two points in an electric circuit. It is measured in volts and is responsible for the flow of electric current.
An electric generator produces EMF through electromagnetic induction. This process involves rotating a conductor within a magnetic field, which creates a changing magnetic flux. This changing magnetic flux induces an electric current in the conductor, producing an EMF.
The amount of EMF produced by an electric generator is affected by several factors, including the strength of the magnetic field, the speed of rotation of the conductor, the number of turns in the conductor, and the resistance of the circuit.
No, EMF cannot be produced without a magnetic field. The process of electromagnetic induction, which is responsible for producing EMF, relies on the interaction between a magnetic field and a conductor.
EMF is directly related to electric current, as it is the force that drives the flow of electric charges in a circuit. The higher the EMF, the stronger the push on the charges, resulting in a higher electric current.
