Definitions for Magnetic flux and Faraday's Law

  1. Nov 25, 2012 #1
    I was wondering if my understanding on Magnetic flux and Faraday's law was correct or not, is this okay?

    Magnetic flux is the number of lines in a magnetic field (Φ)
    Magnetic field strength (B) is the number of magnetic field lines over a given area B = Φ/A
    Other names for magnetic field strength are magnetic flux density and magnetic induction.

    Faraday’s Law is the rate of change in magnetic flux, or how fast the magnetic flux changes with time, which causes an electromotive force to be induced.
    Ways you could change magnetic flux is by increasing or decreasing the magnetic field strength, increasing or decreasing the area, changing the orientation of the magnetic field with respect to the area.

    Also, is the emf found in faraday's law the same as the emf found in the formula emf = Bvl?
    Is the direction of the current found by lenz's law the same as the direction of current found by the modified right hand slap rule?
    And why is emf measured in volts instead of newtons?


    Thanks
