    Velocity of a bar on parallel conducting rails

    Hey, well the assignment is over now, the correct answer was (Fe*R/B^2*l^2)(1-e^(-b^2*l^2*t/Rm) My final attempt was Fe/m - e^(B^2*l^2*t/Rm) I still got an 88 on the assignment, so its not the worst, thanks for the help though

    Velocity of a bar on parallel conducting rails

    Would the answer to that be v(t) = β/(1 + \alphat)?

    Velocity of a bar on parallel conducting rails

    Thanks for the reply, i was way too tired yesterday and not thinking very well... And i have some, but i really struggle with them (been awhile since i took calculus, and i only took the first half). If Fe is on one side, is the next step to evaluate m(dv/dt) from vo to v, and since it is...

    Velocity of a bar on parallel conducting rails

    Homework Statement A pair of parallel conducting rails a distance l apart in a uniform magnetic field B⃗ . A resistance R is connected across the rails. The bar has mass m and is initially at rest. A constant force F⃗ e to the right is applied to the bar. Find its velocity as a function of...
