AI Thread Summary
The Right Hand Rule (FRHR) is applied in scenarios involving generators, where motion generates current, while the Left Hand Rule (FLHR) is used for motors, where current induces motion. It's crucial to remember that the direction of current flow in these rules is from positive to negative, representing conventional flow. Understanding this distinction helps clarify when to use each rule in Edexcel A-Level Physics questions. Mixing them up can lead to confusion, so focusing on the context of generators versus motors is essential. Mastering these rules is vital for success in physics applications.

Hi,

I was wondering if anyone has any advice on when to use FLHR and FRHR in the Edexcel A - Level Physics, as I'm mixing them up in questions.

Thanks,

Abby

The Right Hand Rule is for a generator, and the Left Hand Rule is for a motor. A generator is where movement causes a current, and a motor is where a current causes movement.

Abby, by the way, I just remembered to mention that the direction of the current for these rules is from positive to negative, the "conventional" flow.
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
