When a wire carrying an electric current is moved in a magnetic field of a magnet the magnetic field induced by the wire reacts with the magnetic field of the magnet causing the wire to move outwards. Fleming's left hand rule helps you to predict the movement. F irst finger - direction of magnetic f ield N-S.

Teaching electricity and magnetism is complicated by the challenge that the magnetic forces are perpendicular to the motion of the particles and currents. This requires a three-dimensional perspective which can introduce a variable of a "wrong" direction. To prevent errors, let us be "right" and use the right-hand rule. Some would claim that there is only one right-hand rule, but I have found the convention of three separate rules for the most common situations to be very convenient. These are for 1 long, straight wires, 2 free moving charges in magnetic fields, and 3 the solenoid rule — which are loops of current. Calling these "rules" is the right name.

Right hand rule. These convenient appendages help us understand the interaction between electricity and magnetism via the Right Hand Rule and the Left Hand Rule. If you point your thumb in the direction of the current, as shown, and let your fingers assume a curved position, the magnetic field circling around those wires flows in the direction in which your four fingers point. You need to contort your hand in an unnatural position for this rule, illustrated below. As you can see, if your index finger points in the direction of a magnetic field, and your middle finger, at a 90 degree angle to your index, points in the direction of the current, then your extended thumb forming an L with your index points in the direction of the force exerted upon that particle.

Share: Facebook Twitter Linkedin. If a current carrying conductor placed in a magnetic field, it experiences a force due to the magnetic field. On the other hand, if a conductor moved in a magnetic field, an emf gets induced across the conductor Faraday's law of electromagnetic induction.

Electro-Magnetic Induction

Fleming's left-hand rule for electric motors is one of a pair of visual mnemonics , the other being Fleming's right-hand rule [1] for generators. 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. When current flows through a conducting wire, and an external magnetic field is applied across that flow, the conducting wire experiences a force perpendicular both to that field and to the direction of the current flow i. A left hand can be held, as shown in the illustration, so as to represent three mutually orthogonal axes on the thumb, fore finger and middle finger. Each finger is then assigned to a quantity mechanical force, magnetic field and electric current. The right and left hand are used for generators and motors respectively.

right-hand rule

The Second finger represents the direction of the induced or generated Current the direction of the induced current will be the direction of conventional current; from positive to negative. Fleming's left-hand rule and Fleming's right-hand rule 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. When current flows in a wire, and an external magnetic field is applied across that flow, the wire experiences a force perpendicular both to that field and to the direction of the current flow. A left hand can be held, as shown in the illustration, so as to represent three mutually orthogonal axes on the thumb, first finger and middle finger. Each finger is then assigned to a quantity electric current, magnetic field and mechanical force.
