Try Integration By Parts \int u dv = uv - \int v du

W = \int \vec{F} \cdot \vec{dx} The expression you had was for Impulse not Work

Magnetic Flux = B dot A Because the Area is constant d\Phi/dt = dB/dt * A cos 20 so emf = N d\Phi/dt We know emf because of ohm's law V=iR Therefore, iR = dB/dt * N * A cos20 dB/dt = (iR)/(NA cos20)

\PhiB = B * A (dot product)

Do I necessarily need a Halbach Array to use the Inductrac design??

I don't know any place that sells Halbach Arrays, and they seem difficult to make, correct me if I am wrong.

I understand induction, but I can't think of any real-life applications of when a toroid would be useful.

Homework Statement When is Translational Momentum Conserved and when is Angular Momentum Conserved?

You can use integration by integrating 1/x and making the upper limit 30 and the lower limit 1.

Sorry for not specifying, but I meant Toroids as in the electricity and magnetism part of physics, such as an inductor or a "round solenoid." Thanks

How do Toroids (inductors) work, and What are they used for (in electronics and/or other physics applications)? Thanks

I would like to make a maglev train for a physics project, but I would prefer it to be simple and for the most part easy to make, as I do not have access to too many supplies. Hopefully, you can help me generate a list of possible ideas with brief explanations on how to construct them and how...
