Right hand rule for magnetic field due to a straight wire. Fleming s left hand rule force on a current carrying conductor placed in a magnetic field or principle of motor. A brass bar suspended between two circular magnets. Flemings left and right hand thumb rules explained electrical4u. From this, we can observe that the left hand satisfies motor, and the right hand generator.

Flemings righthand rule for generators shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field. The direction of the force can be found using fleming s left hand rule. Hold your thumb, forefinger and second finger at right. The fleming s left hand rule and fleming s right hand 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. Lets solve problems in calculating the force directions on move charges in magnetic fields using the lefthand rule. These convenient appendages help us understand the interaction between electricity and magnetism via the right hand rule and the left. 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. The rules are called as fleming s left hand rule for motors and fleming s right hand rule for generators.

Lets practice some problems involving flemings left hand rule to find out the direction of the force on a current in a uniform magnetic field. These rules are called as fleming s left hand rule used for motors and fleming s right hand rule used for generators respectively. To find the direction of the magnetic field use the right hand rule. These magnets are mounted on a clear plastic frame.

Fleming s lefthand rule for electric motors is one of a pair of visual mnemonics, the other being 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. 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. In flemings left hand rule what does the thumb point in the direction of. Whenever a current carrying conductor is placed in a magnetic field, it experiences a force due to the magnetic field. The direction of this force can be found using flemings left hand rule also known as flemings lefthand rule for motors. Flemings left hand rule and right hand rule electricalvoice. This rule is also called flemings left hand rule, after english electronics pioneer john ambrose fleming, who came up with it. Flemings left hand rule motor effect worksheets 3 teaching. Three worksheets requiring students to apply flemings left hand rule, to predict the direction of. Flemings left hand rule and flemings right hand rule.

In both fleming s left and right hand rules, there is a relation between the magnetic field, the current and force. The brass bar is suspended by means of connecting wires which are also used to pass current through it. They were originated by john ambrose fleming, in the late 19th century, as a simple way of working out the direction of motion in an electric motor, or the direction of electric current in an electric generator. Flemings lefthand rule for electric motors is one of a pair of visual mnemonics, the other being flemings righthand rule for generators.
