We have an homogeneus magnetic field that was increased from

*0*to*B*. It induced a certain current (that accumulated to a charge_{f}*Q*) in a circular coil of radius*a*and resistivity [tex]\rho[/tex] constant. The question is, what would be the charge*Q'*when the coil is twisted (not strangled), forming an 8 of radii*a*and_{1}*a*in terms of_{2}*Q*?Thanks for your help
