Homework Help: EMF in a straight wire

  1. May 18, 2016 #1
    1. The problem statement, all variables and given/known data
    If the wire moved perpendicular to a magnetic field as in the fig. then the volt of point a is ( bigger than -smaller than-equal ) the volt of the point b

    2. Relevant equations
    please see the attached files

    3. The attempt at a solution

    Hello ahmed, :welcome:

    PF takes a bit of getting used to. Reading the guidelines can help.
    I can't do anything with your post: there is no question, no relevant equations, no attempt at solution.
    In fact I can't even tell what kind of assistance you want ...:frown:

    What do you mean?
    Firstly,it's about
    E.m.f. induced in a straight conductor ( electromagnetic induction) and fleming right hand rule.
    and I want to know if the voltage of point a is larger than the one of point b or vice versa.

    There are no equations given in the attached file

    A complete statement of your problem should be included the the text of the thread, no matter what is stated in the title. That's why BvU said there was no question given .

    You need to make (show) some attempt at arriving at a solution.

    What is Fleming's Right Hand Rule, and how does it apply to this problem?

    (These Forums can be very helpful for people who are trying to gain an understanding of physics and related subjects. The rules may seem overbearing at times, but they have proven to be effective.)
