imatfaal Posted August 12, 2013 Share Posted August 12, 2013 How do you calculate a magnetic field B? As you will have noted from your question regarding rolling friction - you need to be more precise in your questions. The details of (electric and) magnetic fields make up many weeks work in a physics degree - which bit do you want to know about ? Link to comment Share on other sites More sharing options...

I want to know the part about how you calculate how strong a force is between 2 magnets and the magnetic field, B. Link to comment Share on other sites More sharing options...
imatfaal Posted August 12, 2013 Share Posted August 12, 2013 That's actually a really difficult question to answer - there are many different models, approximations, or constraints that one can use to get to an answer; but a general simple solution is hard to find http://en.wikipedia.org/wiki/Force_between_magnets The force on a moving charge is much more easily calculated and is a good start to reading http://en.wikipedia.org/wiki/Force_between_magnets 1 Link to comment Share on other sites More sharing options...
