for problems 1 )-6 ) , refer to fis I he low , which shows bar magnets falling vertically thru wire loops : a ) b ) Fix ! S N S - -- N Induced EMF's can be represented by inserting barkey symbols In the Baps as shown in diagrams A-C bebw, looking down from above the loops ; CA) ( B ) (C)3) The magnetic field of a very long bar magnet varies very slowly along Its length in its mid point region - see dashed lines in fig 1. In Figla when the macnet's midpoint is in the plane of the loop for Such a massset , the induced EMF is bed represented by ( a ) A ( b) B C ) C 4 ) In Fig 13 , when the entire magnet has fallen below the loop's plane, the induced EMF is hest represented by (a)A (b ) B ( ) C In fis lb , the magnetic force between the coil and the bar magnet (a) is attractive when the entire magnet is above the loop , repulsive when it's below the loop ( B ) is repulsive " when the entire magnetic above , attractive when its below ( c ) is attractive in both cases ('d ) is repulsive in both cases (e ) vanishes at all times " ) The energy stored in the B field , produced by induced currents in the loops, originates from work done by the gravitational force on the magnet
