Why and how does magnetic force and field influence a current carrying wire?
Answer The thing that is special about magnetic fields is that the force exerted on a charged particle moving through a magnetic field is always exerted perpendicularly to the path of motion of the particle through the magnetic field. 1. If a magnetic field is directed vertically downward while a positively charged particle moves horizontally North through that magnetic field the direction of the resulting force can be found by using the “right hand rule”. If you point the thumb of your right hand in the direction of the motion of the charged particle [north] while pointing the fingers of your right hand in the direction of the magnetic field [down] the resulting force on the positive particle will be pointing in the direction of the palm of your right hand [west]. 2. Because the magnetic force is always perpendicularly to the direction of motion of the particle, the resulting force will be centripetal! That means that a particle moving perpendicularly through a uniform magnetic field
