Magnetic flux in a straight wire to a cylinder

AI Thread Summary
To determine the total magnetic flux through a cylinder surrounding a straight wire carrying a current of 3.00 A, the magnetic field must first be calculated using the formula B = (μ₀I)/(2πr). The area of the cylinder is essential for calculating the flux, which is given by the equation flux = BAcosθ. The angle θ is zero since the magnetic field lines are perpendicular to the surface of the cylinder. The discussion emphasizes the need to find the magnetic field before proceeding with the flux calculation.

Homework Statement



A long, straight wire carrying a current of 3.00 A is placed along the axis of a cylinder of radius 0.500 m and a length of 5.00 m. Determine the total magnetic flux through the cylinder.

Homework Equations



flux=BAcostheta

The Attempt at a Solution


i found the area of the cylinder first and i don't have any idea where to go from there. I am not really finding any helpful equations...

Obviously, you have to calculate the magnetic field due to the current.

would i use B= (Moconstant)I/2pir??
 
Yep.
 

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}...
