    The EMF induced in straight current-carrying conductor

    Thank you I think I understand, just to clarify I can make a "loop" while moving the wire forward and backward( to make the loop) as I move it up and down between the magnets, it will produce no emf because the direction of the current will be the same as wire's movement whether forward or backward.

    The EMF induced in straight current-carrying conductor

    but this doesn't work for a coil, if i replaced the straight wire with a coil already in the magnetic field and moved it the same way with no rotation no emf would be induced. why is it different for a coil and a straight current carrying conductor

    The EMF induced in straight current-carrying conductor

    Why is an emf induced in straight current carrying conductor as it moves at at right angles to a uniform and constant magnetic filed. By Faraday's law, this e.m.f. is equal to dΦ/dt but I do not understand how a wire cutting a uniform magnetic field experiences a change in magnetic flux . Its...

    Why does a change of magnetic flux induce an EMF?

    Please explain as simply as you can, if you reference something I don't understand I'll ask for clarification

    Why does a change of magnetic flux induce an EMF?

    How and why does a changing magnetic flux induce an emf? Why doesn't a static one also produce one? How are the electric and magnetic forces related? Why do you move a wire through a magnetic field so that the wire, the motion, and the magnetic field are all mutually orthogonal in order to...

    Voltage between two points on an empty wire and also across a resistor

    i thank everybody for all your answers i will do further research into the topics mentioned. thank you again

    Voltage between two points on an empty wire and also across a resistor

    In a closed circuit the battery sets up a potential difference which causes charge to flow. I understand potential difference as the measure of electric potential energy per unit charge, the amount of energy required to move a charge from one point to another per charge. for example when a...
