Motor Effect/magnetic field strength prac! (1 Viewer)

[whimagent]

So its almost done and all I need to do is worry about the conclusion.

The prac is the one with an electronic balance and 2 bar magnets.

So in the conclusion I describe how the mass reading on the scale increased/decreased once a current was introduced in the wire between a magnetic field demonstrates the motor effect. (could someone word this better please?)

I talk about the reliablility, accuracy and validity of the prac.

I give some errors like: (and need moar)

sin theta was assumed to equal one, but most likely isnt - > explanation? > solution?

And I was unsure about the value using 9.8 as g. This probably isn't accurate and hurts accuracy.

Please help on errors and conclusion fix up / more points.

Thanks in advance.
