Is there any way possible a magnetic field can cancel out an electric field?
Thanks !
Thanks !
Are you familiar with the Lorentz force? What can you tell us about your question?Is there any way possible a magnetic field can cancel out an electric field?
Thanks !
Because the E field points up, the electric force on the electron is down. Therefore, to cancel the electric force with a magnetic force, the magnetic force has to point up.More specifically, I don't understand this statement: "The magnetic force, in order to cancel the electric force, must point upward" ???????
I am still having hard time understanding why if a magnetic force points in the same direction as an Electric field, it will cancel?Because the E field points up, the electric force on the electron is down. Therefore, to cancel the electric force with a magnetic force, the magnetic force has to point up.
The electric force on a *negatively* charged particle is in the opposite direction as the Electric field. Look at the Lorentz Force equation:I am still having hard time understanding why if a magnetic force points in the same direction as an Electric field, it will cancel?
