Why Does Fleming's Right Hand Rule Give an Upward Force on the Wire?

AI Thread Summary
Fleming's Right Hand Rule indicates the direction of force on a current-carrying wire in a magnetic field, but in this case, the user found that it suggested an upward force, which contradicted the expected answer. The discussion highlights the need to apply Fleming's Left Hand Rule instead, as it is more appropriate for determining the force direction on the wire. A suggestion to consult additional resources, such as HyperPhysics, was made to clarify the concept. The conversation emphasizes the importance of using the correct rule for the specific situation involving magnetic forces. Understanding the distinction between the two rules is crucial for accurately solving problems related to electromagnetism.

Fleming's hand rules

The Attempt at a Solution


I used the Flemings right hand rule but that gives me that the force on wire is upwards. But the answer is otherwise. Thanks for your help!

You have to apply Fleming's Left hand rule to determine direction of force on current carrying wire .

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
