Where Does Lenz's Law Apply in an Automotive Setting?

AI Thread Summary
Lenz's Law explains the direction of induced current when a magnet moves through a coil, stating that the induced current will oppose the change in magnetic flux. In the discussed scenario, as a bar magnet falls through a coil, the induced current flows anti-clockwise towards the datalogger, indicating a reaction to the magnet's approach. This principle can be applied in automotive settings, such as in regenerative braking systems where the motion of the vehicle generates electricity to recharge the battery. Understanding Lenz's Law is crucial for optimizing energy recovery and efficiency in electric and hybrid vehicles. The discussion emphasizes the practical applications of this law in real-world automotive technology.

A bar magnet is dropped from rest through the centre of a coil of wire which is connected to a resistor and datalogger.

The resistor and datalogger are to the left in the diagram, and the coil on the right side.

Add an arrow to the wire to show the direction of the induced current as the magnet falls towards the coil.

The arrow is drawn going towards the datalogger side (left side) i.e. anti clockwise.

How is this worked out?

First and foremost, the key is in what Lenz's Law states.
Ponder over what Lenz's law says - and try to apply it to the situation here.

So a current is induced upwards, and that goes anti clockwise?
 
Is anyone able to tell me were lenz's law would occur in an automotive situation
 

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}...
