Question

QUESTION 6 A stack of neodymium button magnets (12 mm diameter, 75 mm tall) dropped from 0.200 m high, generates an average +2 375 Volt for 0.040 seconds, as it enters a lab coil that has 800 turns spread along 40 mm tall, each with 0.112 m circumference (28 mm long x 28 mm wide) ja) how much voltage aggregates along each loop?] b) if the stack's magnetic North pole was down, what direction of Electric field was induced as the stack entered (as seen from above)? LC) Compute the magnetic field inside the magnet stack] [d) it the stack takes 0.035s to exit the coil (downward), what average voltage would be generated? counter-clockwise (as seen from above) upward backward away from chalkboard) forward toward clalkboard) downward ОО clockwise (as seen from above)

Answer 1

I have solved your problem which is shown beloW:

Given that Magnets 12mm diameter 75mm tall hought 0.2 m generates - 2.3 7SU ta 0.04 sec n- 8uo turn La homm Concumfrienu: 0.122m (Q1 Voltage along each look +2.375 000296 V 800 Counter رط) Clockwise [as seen from above] S Counter clockwise
