Magnets- lenz's law-figure out V.

Homework Statement



A baar magnet inserted into a coil of 500 turns induces a potential difference of 1.5 V across the coil. Determine the induced potential difference when;

a> 250 turn coilis used.
b> the bar magnet is moved twice as fast through the coil.
c> three identical magnets are inserted at once, side by side
d> all three of the above charges occur simultaneously.



The Attempt at a Solution



a> 1.5V/ 500 = V/ 250
solve for V, V= 0.75 V

b> im not quite sure, Im guessing there will be no difference in the voltage?

c> (0.75V)(3) = 2.25V

d> do I just add the voltages from a, b, and c?

I would greatly appreciate it if anyone could confirm the answers I got or let me know if Im on the right track with b and d?

Thankyou in advance!
