# Fleming’s Left Hand Rule

Show/Hide Sub-topics (Magnetism & Electromagnetism | O Level)

When a conductor carrying a current is placed in a magnetic field, the conductor experiences a magnetic force.

• The direction of this force is always right angles to the plane containing both the conductor and the magnetic field, and is predicted by Fleming’s Left-Hand Rule.
• F is Force, B is Magnetic field, I is current.
• From the name of the rule, use your left hand.

E.g. If current flowing towards to right and the magnetic field is pointing into the paper, the direction of the force is predicted by the Fleming’s left hand rule to be upwards.

1. Oh man! Check ur eg part it says like this “E.g. If current flowing towards to right and the magnetic field is pointing into the paper, the direction of the force is predicted by the Fleming’s left hand rule to be upwards.”current should b pointing into the paper right not magnetic field

• no when the current is to the right, then you have to turn your hand while maintaining the right angled structure so that your index finger, which is the direction of the magnetic field will point towards the screen. when you do this your thumb points upwards, so the direction of current is up….. ik ur qs is from 2014 but i had nothing else to do soooo yea
