Current in wire in Magnetic field[Easy QUICK question]

AI Thread Summary
When a long straight wire is moved toward the left in a magnetic field, the direction of the current flow is debated. Using the right-hand rule, one participant suggests that the current flows into the page, while another argues it flows out based on the force equations. The confusion arises from the treatment of force as magnetic rather than velocity. Clarification is sought on the conditions required for current generation in a conductor within a magnetic field. Ultimately, both methods point to the current flowing into the page, emphasizing the importance of correctly applying the right-hand rule.

Homework Statement


Suppose a very long straight wire were held perpendicular to the plane of the page such that it intersects the page at point D. Additionally, suppose the wire was being moved toward the top of the page.

Suppose instead that the wire were moved toward the left side of the page. Would the current through the wire flow into the page, out of the page, or not at all?

Homework Equations


Right hand rules. F=qv x B. F= IL x B.


The Attempt at a Solution


I think this is into the page. I used qVxB. My index finger is going to the left. Middle finger straight. So the force is down. The force pushes positive currents into the page. Is this correct? My other way was F= ILxB. But it gave me out of the page. I think it's because I treat the force as the v. But I think that's wrong because that F is magnetic. Thank you for the help. This is a little urgent

Good Morning OrangeFruit,

In order for a current to be generated in a conductor due to of magnetic field, what are the conditions?

both of these point into the page... F=q*vxB where q is positive... but the current is due to negative charges so here the equation is F=-q*vxB=-ILxB...
 
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 '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...
