What kind of force does a current going through a wire produce?
What does he mean by that!!? does he mean electrical force? I don't really understand what the question is asking.
help? please?
Oh and any other questions on the worksheet you guys have can post here too.
must...reinforce.....creation....

I'm not exactly sure, but I think he means what way is the force traveling. For example, positive to negative, or negative to positive.

Also what's 3A of current, like in problem 5??? i think that the 9 V is the AA battery but how much power is in it? i don't get it. I also don't understand how to solve 10, and 11, though i know the formula.

power = voltage x current

When you wrap a wire around a nail, what kind of force do you produce? In other words, what's the force that allows you to pick up paperclips with the nail and the current?

On questions 10 and 11, does anyone know what he means by "10 inch radius turn? " The formula is l2=l1+(2)(pi)(b). It never mentions radius.
Assume the inner turn, l1 is 10 inches, since you're trying to find l2 and are given b.

what are the threee alternative drives?? is it asking about differential and steering, but that is only two...but there are 6 of the alternate ones, do we pick 3? or am i missing something?
Steering and Differential drives are standard, pick three alternatives and describe how they work.

On question 7 i am confused as to what you mean by shortcircuiting a motor, do you mean the one where you stop it or the one where you basically fry it?
Oh how wrong we were to think that immortality meant never dieing ~ MCR

On number two i think its talking about the magnet itself.

Short circuiting basically mean stopping the motor. I don't think they will really ask a question about frying one. :-)
