The magnetic field produced by currents in wires ... The force on a charged particle in a magnetic field ... The magnetic field is a vector, the same way the electric field is. The electric field at a particular point is in the direction of the force a positive charge would experience if it were placed at that point.

When you wrap the wire around the nail, make certain that you wrap the wire all in one direction. You need to do this because the direction of a magnet field depends on the direction of the electric current creating it. ... The movement of electric charges creates a magnetic field. If you could see the magnetic field around...
