1. The problem statement, all variables and given/known data Rectangular loop with resistance R is spinning with angular velocity ω in the homogeneous magnetic field with a density of B. What is the electric current flowing on the loop? With what average torque do we have to turn the loop? Picture: http://item.slide.com/r/1/254/i/Cs-60nN37T_tSYvw3YSe_Qmz8ovH2qaG/ [Broken] 2. Relevant equations V= ω*sin(ωt)*B*S I= V/ R τ= m*B 3. The attempt at a solution p(m)= S*I p(m)= (ω*S²*B* sin(ωt))/ R m= p(m)*B*sin(φ)= p(m)*B*sin(ωt) m= (S²*B²* ω*sin(ωt)²)/ R τ= m*B Are my equations correct? Thank you for helping!
