A rod with resistance $$R$$ lies across frictionless conducting rails in a constant uniform magnetic field $$B$$, pointing out of the paper. Assume the rails have negligible resistance. The magnitude of the force that must be applied by a person to pull the rod to the right at constant speed $$v$$ is: $$\begin{array}{l}{B}^2{L}^{2}v(x/R)\\ BLv\\ BLv(x/R)\end{array}$$ No force (zero Newton) $$B^2{L}^{2}v/R$$ Question 4 (1 point) A 14-turn ideal solenoid has an inductance of $$\left(2.2\times 10^{?}0\right)\mathrm{mH}$$. When the solenoid carries a current of $$\left(4.58\times 10^{?}0\right)\mathrm{A}$$. What is the magnetic flux through each turn? Note: Answer in scientific notation using $$Wb$$. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: $$x10$$ Answer
