How Does Magnetic Force Affect a Wire in a Field?

AI Thread Summary
The discussion focuses on calculating the magnetic force acting on a wire carrying a current in a magnetic field. The wire, oriented along the x-axis, has a current of 2.3 A flowing in the positive x direction, while the magnetic field is 0.82 tesla in the positive y direction. The relevant equation for determining the force is F = I * L x B, where L is the length of the wire in the magnetic field. Participants highlight the challenge of determining the appropriate length L to use in the calculation. Understanding the interaction between the current and the magnetic field is crucial for solving the problem effectively.

Homework Statement


A wire is oriented along the x-axis. It is connected to two batteries, and a conventional current of 2.3 A runs through the wire, in the +x direction. Along 0.27 m of the length of the wire there is a magnetic field of 0.82 tesla in the +y direction, due to a large magnet nearby. At other locations in the circuit, the magnetic field due to external sources is negligible.
What is direction and magnitude of the magnetic force on the wire?


Homework Equations


no clue

The Attempt at a Solution


nothing?
 
Physics news on Phys.org
There is an equation that relates the force on a wire of length L to the current I flowing and the magnetic field strength B. See if you can find it.
 
F=I*LxB?
 
Yes, that's the one.

The tricky part is what to use for L.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
