Difference between a magnetic field and an electric field

  1. Jan 22, 2011 #1
    1. The problem statement, all variables and given/known data
    Describe the difference between a magnetic field and an electric one.



    2. Relevant equations
    N/A


    3. The attempt at a solution
    I thought the two were the same or at least linked somehow. I don't understand why a proton will not achieve an increase of decrease in Ek when going through a magnetic field, but will under an electric field.
