(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Use the law of electromagnetic induction to deduce what typical voltage would be imposed in the magnetopause by the interplanetary magnetic field, assuming a scale size of the magnetopause of 10Re?

2. Relevant equations

-Magnetic flux equation

-Faraday's law

3. The attempt at a solution

See attachment for solution.

I took the interplanetary magnetic field strength to be 10^-9T (is this right?) and assumed that the magnetopause rotates at the same rate as the Earth.

Did I get it right? I normally do this sort of calculation for conductors rotating in a magnetic field. In this case one magnetic field is imposing an emf on another magnetic field. Did I have to take into account the strength of the magnetopause?

Thanks a lot for any advice.
