Help me please about Fleming's Rule

  1. Aug 3, 2010 #1
    I am not sure about Fleming's Rule

    The difference between Fleming's Left Hand Rule and Fleming's right Hand Rule.
    Fleming's left hand rule there or not ? I think ,there are only Fleming's right Hand Rule.

    I've never heard of the left hand rule. I've only used the right hand rule for figuring out the movement of particles in magnetic fields. For negative particles, you just use the right hand rule as usual, and flip the direction of the particles movement at the end.

    For left hand rule, I not sure >>> http://en.wikipedia.org/wiki/Fleming's_left_hand_rule_for_motors

    Bear in mind that the orientation of B field is just a convention.

    Some teachers of mine use an adaptation of the left rule to determine the direction of certain forces - they say it avoids confusion, but I don't share this opinion.

    it is very easy, you can apply fleming's left hand rule, when current produces motion in the wire under the external magnetic field. e.g, when you tun on the switch , the fan begins to rotate, electric motor also doing the same, but fleming's right hand rule, when motion produces current in the wire under the external magnetic field. e.g, electric generator. when water falls on the turbine the coil rotates under the magnetic field , the current produces
