Homework Statement Why is it that when a charged object is near a stream of water (polar), it causes the stream to bend towards the object (attraction) instead of bend away (repulsion)? I know why the water bends, but why does it not REPEL instead? Homework Equations N/A just an...

oh crap i messed up, ignore the N's, they are all in Joules!

the non magnetic is 0.018N, the magnetic is 0.048N which is the same as change in gravitational potential energy

It does, but only for the magnetized disk. The non magnetized disk has a different (smaller) energy lost. Why is that? should they be the same?

So what would the values be in the equation for both scenarios? Eg1 - Ek2 = E lost m= 0.01kg t (NON MAGNET) = 0.80s t (MAGNET) = 5.2s v (NON MAGNET) = 2.5m/s v (MAGNET) = 0.19m/s thanks

But the value of energy lost does indeed change, since the energy lost equation requires kinetic energy which require velocity, and the velocities for each scenario is different. I was told by others that Normal force gets bigger. The normal force is counteracting not only gravity now, but...

Say if an iron disk slides down a non ferromagnetic conductor ramp and we get a certain time. And then we have an iron disk with the same mass but MAGNETIZED slide down the same ramp and get a longer time (because of of magnetic braking). The calculated acceleration of the MAGNETIZED disk will...

I think both: push up at the beginning, pull down at the end. Since Faraday says flux (from magnet?) induces a current, and Lenz says that this current opposes the change in flux, therefore it should be trying to get rid of the magnet. Right?

Magnet dropped down a copper tube experiment (magnetic braking?) Homework Statement Experiment: what is the effect of the # of magnets on the time of drop through the pipe? Magnets are placed in a paper cylinder container - "one magnet" is 1 magnet and 5 weights (mass of 1 magnet and 1...
