AI Thread Summary
Fleming's Left Hand Rule and Right Hand Rule serve different purposes in electromagnetism, with the left rule applicable for motors and the right rule for generators. The left hand rule helps determine the direction of force when current causes motion in a wire within a magnetic field, while the right hand rule indicates the direction of induced current when motion generates electricity. Some educators advocate for an adaptation of the left hand rule to reduce confusion, although this view is not universally accepted. The discussion highlights that the orientation of the magnetic field is a convention and can affect the application of these rules. Understanding both rules is essential for grasping the principles of electromagnetism and their applications in devices like motors and generators.

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
 
any body know about induce emf
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
