your thumb will point to the diretion of the rotation...and you forefinger will point to the direction of the magnetic flux
AnswerFleming's Left-Hand Rule applies to motors when using 'conventional flow' and to generators when using 'electron flow'. So, assuming you are talking about electron flow, the thuMb indicates the direction of Motion of the conductor relative to the flux, the First finger indicates the direction of the magnetic Field (north to south), and the sEcond finger indicates the direction of the E.m.f. induced into the conductor. This applies whether the generator as an a.c. machine or a d.c. machine.

When you're using the right-hand or generator rule your middle finger indicates the direction of what?
conventional current flow
What are the hand seal combinations for chidori current?
chidori hand signs the use presure.
What is the rule relating to the direction of the field due to the current in a wire?
The "Right Hand Rule" Put your right hand under the wire with your thumb sticking out and in the direction of the flow of the current (note that it is opposite to the direction of the movement of the electrons!) and close your fist; the fingers of the right hand will curl around in the direction of the magnetic field.
What is formed around a wire when electricity flows through it?
Current through a conductor forms a magnetic field.The "Right Hand Rule" will tell you the direction: Point the thumb of your right hand along the conductor in the direction of current flow (from negative to positive) and the fingers of the right hand curl in the direction of the magnetic field force lines.
Why does the hair on the hand stands straight when you sit before tv?
This sounds like a very weak electrical current is passing from the TV to you.
What does an electric hand dyer use to run?
it is powered by alternating current, or electricity
What uses a magnet to change mechanical energy into electrical energy?
It's called a generator. Most of them spin a magnet within a coil of wire, which induces a voltage in the coil. The size ranges from something that you can hold in your hand to big multi-ton giants that are used in power plants. Every automobile has a generator in it. These are usually referred to as "alternators," since they produce alternating current, but the principle is the same.
When you're using the right-hand or generator rule your middle finger indicates the direction of what?
conventional current flow
How many directions does alternating current flow?
The frequency of direct current (DC) is 0 Hz. The current only flows in one direction, like the electrical system in your car. On the other hand alternating current (AC) as it suggests alternates back and forth from source to load and when graphed it looks like a sine wave. The frequency of this current can vary depending on the source and it's application. Take your house hold electrical system for example, it is AC current with a frequency of 60 Hz (in North America), which means that you will have 60 current cycles a second. There is a lot more to both AC and DC systems and their applications but that's the basic difference between the two.
What energy is used in a hand generator?
Using a hand generator to produce electricity takes 'physical energy' to turn the handle.
Could you generate power by hand generator?
yes, because our hand is one of the type of conductor
What is Dc generator principles?
Fleming's right hand rule.
What machine converts kinetic energy to electricity?
-- Hand-crank generator -- Hydroelectric generator -- Windmill generator -- Front-wheel generator on a bicycle -- Car generator, run by a belt from a wheel on the crank-shaft -- Any turbine generator, i.e. turned by a shaft which is forced to turn by anything else
What is the relation of Fleming right hand rule in AC Generator?
gfchs
How are magnets used in generators?
There are two types of generators. First is Alternative current generator and second is Direct current generator. In both types of generators horseshoe-type magnets are used. This magnet is used so that when the shaft is rotated in anticlockwise direction the direction of force is upwards and the magnetic field lines are going from north to south or left to right. By using flemings right hand law the current wil flow from west to east. This magnet makes the current to flow in a circuit consistently to produce electricity.
How do you flash the field of a generator?
start generator, plug in variable speed drill, set drill to forward, squeeze trigger, quickly spin drill in reverse by hand. be sure generator main breaker is on.
What is the difference between motor and generator in electrical machine?
A motor converts electrical energy into mechanical energy and a generator converts mechanical energy into electrical energy.Longer answerThe primary difference between a motor and a generator is that one converts electrical energy into mechanical energy (that's the motor) and the other converts mechanical energy into electrical energy (that's the generator).In some cases of direct current (DC) machines, but not alternating current (AC) machines, there is so little difference that a single device (it might be called a motor-generator) can be used as either a motor or a generator.A superb example of this would be the motor-generator that is used in electric vehicles: when the vehicle is accelerated, the batteries supply power to the motor-generator and it acts as a motor, driving the wheels. When the brake is applied, the motor-generator shifts function and the vehicle's inertia is used by the motor-generator to generate electricity and put some energy back into the batteries. This slows the vehicle down. The one device (the motor-generator) is being used in either capacity. The "handle" often applied to electric vehicles with this feature is dynamic braking.They alike because they both have stators and rotors they are different in that the generator is driven by mechanical device that rotates the rotor, the rotor cuts through magnetic force fields and electricity is generated. The motor is driven by an input of electricity into the stator and the rotor is forced to turn by reaction with magnetic force fields.Generator will provides current to load ......... but motor will drawn current............... generator is based on Flemming right hand rule but motor is based on left hand rule.
