Two current carrying wires perpendicular to each other

AI Thread Summary
When two long wires carrying current are positioned perpendicularly, they generate magnetic fields that interact with each other, resulting in forces acting on both wires. The direction of these forces can be determined using the right-hand rule, where the thumb points in the direction of the current and the fingers indicate the magnetic field direction. The force on each wire is perpendicular to both the current direction and the magnetic field created by the other wire. Understanding this interaction involves visualizing the forces at the points where the wires cross, which can be represented as a diamond shape with the intersection at the center. This conceptual framework helps clarify the nature of the forces between the wires.

two long wires carry current and are at right angles to each other, but they do not touch. describe the force between them

I found the magnetic field and force direction individually when one wire's current points north and the other east. I just don't quite understand the affect they have on each other. It's a concept problem. I understand the force on each other in parallel.

You just have to do v \times B (v cross B) to find the directions. Draw the cross, and look at the direction of the forces on each wire on both sides of the crossing wire (e.g. 4 points in a diamond with the crossing point at the center).

Does that make sense? Or help at all?

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}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
