Direction of induced current question

AI Thread Summary
In the discussion about induced current in a conductor placed between a north and south magnet, the scenario involves a metal pole oriented perpendicular to the magnetic field. The upward force on the conductor leads to the question of the direction of the induced current. The left-hand rule suggests that the current flows from the top (X) to the bottom (Y) of the pole. However, there is a conflict regarding the induced current's direction, as the upward force would imply that the induced current should create a magnetic field opposing this change, potentially indicating a downward force. Clarification on the application of the right-hand rule for induced electromotive force (emf) is also mentioned.

Homework Statement


There is a conductor; a metal pole say, in between a north and south magnets. North on the left, south on the right.

The conductor is layed out in such a way that it is perpendicular to the magnetic field lines going from north to south. Let's label the metal poles X for the TOP of the pole Y for the bottom.

There was a force exerted on the conductor in the UP direction, lifting it.

A current was induced due to this force, which way was the current flowing?

The Attempt at a Solution



From the "left hand rule" (basically if magnetic field is in one direction, the force is perpendicular to it, and the conventional current is flowing perpendicular to them both, its a pretty common rule)

Im lead to believe that the current will be flowing from X to Y.

HOWEVER a conflicting idea caught me. If the FORCE exerted to LIFT the object was in the upward direction, wouldn't that mean that the induced current would create a magnetic field to OPPOSE this change? Thus wouldn't the force actually be DOWNWARDS?

Here's a picture:
Not sure if itl'l work, thus i included a description above

Left hand rule is used to find the direction of force on a current carrying conductor in a magnetic field. For the direction of induce emf, you have to use "right hand rule".
 
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...
