left hand and right hand rule???Watch
left hand rule is used to find force
right hand rule is used to find current (I)
I'll go away now and back to chemistry (much safer territory for me!)
motors are machines that change electromagnetic energy into kinetic energy, i.e. currents and voltages into motion; dynamos are machines that change kinetic energy into electromagnetic energy, i.e. motion into voltages and currents.
first finger field
second finger current
Fleming’s Left Hand Rule
Used when a current from an external source flows through a conductor in a magnetic field, resulting in a force.
motors drive cars and we drive on the left
Fleming’s Right Hand Rule
Used when an external force produces a motion on a conductor in a magnetic field, inducing a current to flow in the conductor.
Other Right Hand Rule
Point thumb in direction of current; fingers show direction of magnetic field.
You get a “thumbs up” when you are right!
