I put up then changed to right

eesh, got that wrong then .-.
The copper would go to the left ? The convectional current is coming towards you and the dirrction of magnetic field is down so your thumb ends up facing right?

u gott hat too?
i thoguht cuz like it goes bakwards or something
there was something about how to make the copper or somat more faster i think
did anyomne say to add xtra current

Yes you were meant to explain what the effect of increasing the current has on the motor I think.

Compass points north when not near a magnet
This shows that the earths core must be magnetic as it generates its own magnetic field
I don’t know if that’s right though

arrow goes left, no? .-.
lool think everyone got different answers

The convectional current is towards you tthe mahnetic field is down so the force is to the right

oh, right
heh, lol i think i got all the 1 markers wrong jtudt
What did you get on the wave length question

What did you get on the wave length question

which one?
Original post by A____J
which one?

The one where you need to measure it

I think it was llike 4mm =1mm

What did you get on the wave length question

I measured between the ending 2 rarefactions not the ends of the waves getting me 10cm which is 100mm which means its 500mm. Then i divided it by like 7 or 8, the amount of waves between them getting me like 71.something. there might be a range of answers tho not sure if im right
