why the direction of the current is determined by which way you move the magnet through the coil?
explain deeper please. Thank you.ice109 said:because there is a negative sign in faraday's law
I did not understand anything. I want text, not forumulas.mcstar said:hello!
i mention it here too, because its a newer thread:
i worked out the problem with the coil.
its here:

I am interested about the electrons. I don't need equations.mcstar said:so what the fsck do you want?
hm?
there are the graphs, showing the current vs time.
and formulas are neccesary.
what do you want to undertand, if you are not familiar with the basics?
The direction of the current is determined by the Lorentz force, which describes the force exerted on a charged particle by an electric and magnetic field. When a magnet is moved near a wire, it creates a changing magnetic field which induces an electric field in the wire. This electric field then exerts a force on the charged particles in the wire, causing them to move and creating an electric current.
Yes, the direction of the current will always change when a magnet is moved. This is because the changing magnetic field will always induce an electric field in the wire, which will then cause a current to flow in the opposite direction of the magnetic field.
Yes, the direction of the current can be reversed by moving the magnet in the opposite direction. The direction of the current is always determined by the direction of the changing magnetic field, so by moving the magnet in the opposite direction, the changing magnetic field will also be reversed, resulting in a current flowing in the opposite direction.
The direction of the current is important because it determines the flow of electricity in a circuit. In electrical devices and appliances, the flow of current is crucial in order for them to function properly. Understanding the direction of the current is also important in designing and building electrical circuits.
No, the direction of the current cannot be controlled by moving the magnet at different speeds. The direction of the current is solely determined by the orientation and movement of the magnet, not the speed at which it is moved. However, the strength of the current can be affected by the speed of the magnet due to the rate of change in the magnetic field.
