    Formula for calculating current and or voltage in a coil

    A cylindrical magnet with axial magnetisation oriented according the aes of the coil will fiinally find an equilibrium in the centre of the coil.

    Why do two wires with currents in the same direction attract?

    Acording the contraction theory it seems that the density of moving electrons with respect to each other becomes higher. That all and explains the excistings of the magnetic field. The magnetic field is a kind of derivative of the force acting between charged bodies.

    Formula for calculating current and or voltage in a coil

    The current will be dominantly determined by the supply voltage U and the resistance R; it will rise to U/R in less than 1 millisecond being self inductace L over R; the self inductance can be determined with a book, Grover Inductance Calculations. So your supply voltage is the key. I expect 0.5...

    Why do two wires with currents in the same direction attract?

    The total amount of charge remains zero for both wires. The fact that charges is moving leads to a relativistic effect, causing the Lorentz force.

    Formula for calculating current and or voltage in a coil

    For a long coil one will not notice an induced voltage; only at the ends, because then the coupled flux changes rapidly.
