Induced Current in a Circuit by a Moving Magnet

AI Thread Summary
The discussion focuses on calculating the power supplied to a zero-resistance slide wire and the induced current when a magnet moves in a magnetic field. The power is determined using the formula that multiplies the pushing force by the velocity, yielding a value of 3.13*10^-4. To find the induced current, the motional EMF is calculated using the equation E = vBL, leading to the induced current formula I = E/R = vBL/R. The participants clarify that while resistance is known, the induced voltage must be derived from the motion of the wire in the magnetic field. The conversation emphasizes the correct application of formulas to solve for the induced current.

A 10-cm-wide, zero-resistance slide wire is pushed toward a 2.0 ohm resistor at a steady speed of 0.50 m/s. The magnetic field strength is 0.50 T. How much power does the pushing force, 6.25*10^-4 supply to the wire? What is the magnitude of the induced current?

I got 3.13*10^-4 for the first part, which is probably correct because it's a simple formula. Just the pushing force times the velocity. However, I cannot figure out how to determine the second part of the question.

I=V/R

While R is given, V is not because it's an induced current. I'm so confused. Help please?

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.
