A magnet will not repel charged particles, but it will deflect them. The force on a moving charged particle will be at a right angle to the direction it is moving in. In a uniform magnetic field, charged particles will ultimately move in circles.
My project is to create a device that will accelerate the air ions in one direction and to calculate their acceleration.
To see how the charge on the electron was originally measured, see: http://en.wikipedia.org/wiki/Oil_drop_experiment [nofollow]Air is (mostly) an insulator, so it is very hard to measure a flow of ions with a current meter, unless you create extra ions with a source, like a spark or a radioactive source. Air can be turned into a conductor by applying a voltage of > 1 Megavolt per meter. But then it sparks over, and the current is (momentarily) so high that it is very hard to measure.Warnings: Be very careful with high voltages (over 160V DC). By using plates very close together, you can create a strong electric field gradient, without using excessively high voltages.
Would there be another way to ionize the air first using high voltage and then create a negatively charged plate to accelerate these newly ionized molecules.
would this work for accelerating and creating the ions. with the enamel on wire on the inside of the tube stripped to allow the current to flow freely through the air acting as an electrode.
would this work for ... creating the ions.
would changing the medium that is being ionized allow for increased visibility such as submerging the device in water or oil?
I thought that the water wouldn't work just wanted to make sure. If I have the metal plates in my diagram 1.27 cm apart and i have the electrode 1.27 cm away from the plate could the corona discharge damage the source of hv?
is there another high voltage from low voltage generator I could create?
I was hoping to get a large enough density of air molecules ionized that the movement of air would have an impact on other objects that could be used to determine their velocity. As for the voltage i was hoping to have a controllable voltage source that would allow me to see the differences the voltage has on the speed of the ions.
My goal is quite similar to that, but I was hoping to make one more powerful so that it could push for example a soccer ball. then test how much the voltage attached affects the force and to see if the device can be scaled up.
assuming only one electron of charge is added to each molecule
Maybe not a single charge, but I'm pretty sure that varying magnetic fields can accelerate a plasma.
