Document Summary
Charged particles moving through a magnetic field are deflected o. In vector form, magnetic force is written as . o: again, use the right hand rule. Magnetic force on a moving charged particle (magnitude) o o o. It is crucial to note that only the component of v perpendicular to b determines the magnitude of the magnetic force. Direction of magnetic force and charge sign: for negatively charged particle, the magnitude is still given by the same equation, calculate force on it first and then flip the sign on the answer you get, example 3. Find the magnetic force in the following 2 special cases of a positively charged particles moving in the magnetic field indicated. F is qvb, out of page (sin 90 =1 ) for the first but for the second is zero: example 4. Magnetic field exerts a force of 8 x 10^-14n towards the west on a proton moving vertically upward at a speed of 5. 0x10^6m/s.
