Homework Help: Magnetic field due to current

  1. Jun 24, 2015 #1
    1. The problem statement, all variables and given/known data
    two proton beams going in same direction repel each other whereas two wires carrying currents in same direction attract each other

    2. Relevant equations

    3. The attempt at a solution
    two proton going in same direction then it makes two current going in same direction. And current going in same direction attract each other in magnetism. But in electrostatic, like charges repel each other.
