Magnetic Force Direction Question

AI Thread Summary
To determine the direction of the magnetic field acting on a wire carrying a current of 21.0 A, with a magnetic force of 0.104 N directed upwards, the right-hand rule is applicable. The wire is oriented at a 10-degree angle towards the north-east, and the magnetic field strength is 0.0720 T. The equation B = IlBsin(theta) can be used to relate the magnetic force, current, and magnetic field, but understanding the vector directions is crucial. The current direction and force direction must be established to correctly apply the right-hand rule. The solution requires careful consideration of these vector relationships to find the magnetic field's orientation.

Homework Statement


r= 0.12m
B = 0.0720T
I = 21.0A
Fm= 0.104 N [up]

A magnetic force of 0.104 N [up] acts on a 12.0cm long wire that runs[N 10 degrees E] through a magnetic field of 0.0720 T. If the current in the wire is 21.0 A, then what is the direction of the magnetic field?

This physics Level is 4U in Canada, or grade 12.


Homework Equations


B = IlBsin(theta)
Not sure what other equations to use.
Right hand rule might be relevant but not sure how to apply it.


The Attempt at a Solution


I am completely stumped and do not know where to start.

You need an equation between magnetic field strength and magnetic force. And watch out because you need to know directions of these vectors as well as just a formula.
 

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 '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...
