Yes it did because when the range is 0 the horizontal speed is 0.did your line of best fit start from 0?
how come velocity doesn't increase again haha this is probs stupid as but I drew an increase in velocity after it leaves the magnet because i thought the direction of eddy currents would change & so the trolley would experience a force in the opposite direction, causing its velocity to gain slightly.
yeah this is what i didIt doesn't decrease through B and C
If you measure the trolley with the A-B-C-D range you'll find both are exactly 3cm
It should start decreasing slightly before since the magnet isn't situated exactly at point B
and since the magnet will continue attracting after the front of the copper has slid through (i.e. the back of the copper bar) it should begin increasing just before D
Lets just say the magnetic field at 0.0001 meters away from the middle is X and right under is Y. Change in flux = X-Y and thus since they're not equal there has to be a change in flux? no?At the point where its directly under? So like the same situation of when you have something moving within a field, and when its completely immersed, has no induced current.
