    Finding the resistive force of a magnet moving along coils

    Jim, Thanks for the response. I apologize, it is a system of coils. I like your last line about opinions! Ultimately I will test a working model. Currently I have experimental data for the project minus the resistive force of the "generator". I plan on using the force in the damping term in the...

    Finding resistive force from a magnet moved over coils

    I'll try this again since my phone apparently wanted to submit that post before I finished typing... I found an answer using a Halbach Array which allowed me to arrange the magnetic field in a way that is perpendicular to the induced current so the cross product is maximum. The resulting force...

    Finding resistive force from a magnet moved over coils

    Thank you for the response. I believe I have figured it out. You are correct that the emf is produced my a change in the magnetic field (faraday's law). If the current is in the same direction as the field lines then the force is equal to zero which is proven by F=qV X B . I believe I found an...

    Finding the resistive force of a magnet moving along coils

    Thank you for the response. I think I have figured it out using the equation f_mag= integral(I dL X B) (sorry I don't know how to type equations from my phone). Using faradays law this equation is then dependent on both the induced magnetic field and the magnet itself which is what I believe you...

    Finding the resistive force of a magnet moving along coils

    Hi everyone! I posted this in the ME section as well but thought this would be a good section as well. I am working on a thesis project and have a question for anyone who feels they can answer it. I am trying to find the resistive force created when a magnet moves along a coil of wire. I have...

    Finding resistive force from a magnet moved over coils

    Hi everyone! I am working on a thesis project and have a question for anyone who feels they can answer it. I am trying to find the resistive force created when a magnet moves along a coil of wire. I have put pictures below but here is the short explanation: The pendulum, which is fixed at a...

    What can I expect from the Physics Forums community?

    Hi everyone, I'm finishing my last semester for a bachelor's in physics and am new to the forum. Just completing the intro as requested in the email. Thanks for any input to future questions!
