Answer 4

LOL

Answer 5

Oh man I haven't done this in years, ok lets see, I should know this!!

Answer 6

what is the trick to the first question?!?!?!?!

Answer 7

Ah ok you have to just label the poles for induced magnetic field and current

Answer 8

yes XD

Answer 9

It's that right hand rule or what ever

Answer 10

Ok actually, so the bar moves through the coil correct

Answer 11

yes !!

Answer 12

:)

Answer 13

So as it moves inside the coil you would have S and N as you had labelled I see those erase marks

Answer 14

wait, ignore the direction of the current...i am not sure if those arrows are correct..

Answer 15

And if it were reverse the poles will switch

Answer 16

cuz i made them....sorry

Answer 17

the diagram is without the arrows..

Answer 18

Answer 21

haha ok, so explain me this question

Answer 22

What are we doing with the bar magnet

Answer 23

i guess we have to assume that the coil doesn't have a magnet inside it but it's just a referrence point to give us the direction

Answer 24

So as the bar magnet moves into the coil as I was saying there will be an induced current! Ah yes Mr. Faraday!

Answer 25

they gave me an exaple like this....
