Homework Help: Using Magnetic field to repel a paper plane AP Physics Project help?

  1. May 26, 2012 #1
    I simply need to shoot a paper plane very far, the furthest distance. I cannot interfere with it during flight. I plan to have copper wires up a standing pole, from the pole, an extension (used as a ramp for the plane to gain acceleration), will stick out less than 90 deg/ Perpendicular). On that extension ramp I will have a linear solenoid setup (permanent mag. in back then a 10mm push solenoid) and a non -charged metal rod in the center of the solenoid ( to be induced) to repel out the plane which will have a magnet in the back of it.

    I would like to ask about the specs. since this is a school project in a AP class; it cannot be dangerous. I plan to conect the copper wires to a AC outlet (120V) and a step down transformer allowing 1.5A to come through. With 1.5A, will that be enough current for the solenoid's magnetic field to repel the plane a long distance, a few feet? Along with gravitational potential as well. The pole is 4-5 up, I could make it bigger. ----Thanks.

    All I'm going to say is when you deal with an outlet, you should always put a fuse in your circuit. Go by a local electronics store and pick up a 3 A fuse, and make sure it is installed before you ever plug your circuit into the wall. It will be something like this:
