These rules are called as flemings lefthand rule used for motors and fleming s right hand rule used for generators respectively. Flemings left hand rule, the motor rule explained with. This video teaches you how to properly use them when solving questions. John ambrose fleming introduced two rules to determine the direction of motion in motors or the direction of induced current in generators. Lets solve problems in calculating the force directions on move charges in magnetic fields using the left hand rule.
Fleming s left hand rule force on a current carrying conductor placed in a magnetic field or principle of motor. This video demonstrates the proper use of fleming s 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. In both fleming s left and right hand rules, there is a relation between the magnetic field, the current and force. Cbse class 10 science magnetic effects of electric current fleming s left hand rule when a current carrying conductor is placed in a magnetic field it experiences magnetic force. Flemings left hand rule and right hand rule electricalvoice. The brass bar is suspended by means of connecting wires which are also used to. These magnets are mounted on a clear plastic frame. Fleming s right hand rule is used to determine the direction of the induced current that flows from the wire when there is relative motion with respect to the magnetic field. From this, we can observe that the left hand satisfies motor, and the right hand generator.
This relation is directionally determined by flemings 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. Download fulltext pdf download fulltext pdf download fulltext pdf a lefthand rule for faradays law article pdf available in the physics teacher 521 december 20 with 1,921 reads. Fleming s right and left hand rule are both used in different situations. Fleming s left hand rules is explained using the catapult effect to demonstrate the force on a wire in a magnetic field going on to examine the interaction of the fields and linking that with. Fleming s left hand rule for electric motors is one of a pair of visual mnemonics, the other being fleming s right hand rule for generators. Fleming s right hand rule states that the thumb indicates the motion of conductor, forefinger indicates the direction of magnetic field and second. Flemings right hand rule electromagnetic induction. The rules are called as fleming s left hand rule for motors and fleming s right hand rule for generators. 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. A brass bar suspended between two circular magnets. These rules were created by john ambrose fleming and are commonly used as memory aids. According to fleming s left hand rule, if the thumb, forefinger and middle finger of the left hand are.
