In both fleming s left and right hand rules, there is a relation between the magnetic field, the current and force. This video will help you recall how to use the fleming s left hand rule in various settings. This relation is directionally determined by fleming s left hand rule and fleming s right hand rule respectively these rules do not determine the magnitude but instead show the direction of any of the three parameters magnetic field, current, force when the direction of. Force is produced such that the coil moves or rotates. These rules are called as fleming s left hand rule used for motors and fleming s right hand rule used for generators respectively. Fleming s right and left hand rule are both used in different situations.
Fleming introduced two important rules to determine the direction of motion or force in case of motor and the direction of induced current in case of a generator. Fleming s righthand rule for generators shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field. From this, we can observe that the left hand satisfies motor, and the right hand generator. Physics difference between flemings right and left hand. The rules are called as fleming s left hand rule for motors and fleming s right hand rule for generators. The fleming s left hand rule and fleming s righthand rule are a pair of visual mnemonics mnemonics are learning techniques or memory aids, such as an abbreviation, rhyme or mental image that helps to remember something. Flemings left hand rule and right hand rule electricalvoice. This again relies on the cross product in the lorentz force, except that now the charges velocity is given by the objects motion, and the force along the wire is what establishes the current. This video teaches you how to properly use them when solving questions. Fleming s left hand rule whenever a current carrying conductor is placed in a magnetic field, the conductor experiences a force which is perpendicular to both the magnetic field and the direction of current. It can be used to determine the direction of current in a generators windings. As we have also learnt fleming s left hand rule in previous chapter electromagnetism, many students have problems in deciding which rule to use. When a conductor such as a wire attached to a circuit moves through a magnetic field, an electric current is induced in the wire due to faradays law of induction.
