Induced magnetic and electric fields question

AI Thread Summary
The discussion centers on the principles behind the movement of magnets and wires in electromagnetic interactions. Oersted's discovery indicates that a current-carrying wire induces a magnetic field that interacts with a magnet, causing it to move due to changes in magnetic flux. Conversely, Ampere's findings show that a changing magnetic field induces an electric field, which interacts with a current-carrying wire, resulting in its movement. The associated forces in these scenarios are crucial, as they are the driving factors behind the observed movements. Understanding these interactions enhances comprehension of electromagnetic theory and its applications.

Homework Statement


1. Oersted discovered that a curernt carrying wire caused a magnet to move. Why does the magnet move?

2. Ampere discovered that a magnet caused a current carrying wire to move. Why does the wire move?


Homework Equations



(i) ∫Edl = - dΦ_B/dt
(ii) ∫Bdl = Iμ_0 + μ_0ε_0(dΦ_E/dt)
(iii) F = qvxB
(iv) F = IBxL



The Attempt at a Solution


1. By eq. (i), a changing electric field will result in a change in magnetic flux i.e. will induce a magnetic field. This magnetic field will react with the magnetic field of the magnet, causing it to move.

2. By eq. (ii), a changing magnetic field will result in a change in electric flux i.e. will induce an electric field. This will react with the electric field of the current-carrying wire, causing it to move.

Do you think these answers are sufficient? Is there anything more to be said?

Hi Pyroadept

Its probably worth mentioning the associated force in each situation, and how the force is created. After all its the force that causes the wire and magnets to move in the first place.
 

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}...
