Write the expression for the magnetic flux through the loop at an instant t if the loop moves with a speed v in a magnetic field B$?(4$pt$)($b$)$ What$$s the magnitude of the magnetic field if the power dissipated in the resistor is P $=2$ W and the loop moves with speed v $=10$ m$/$s$?(5$pt$)($c$)$ What$$s the direction of B~ if the induced current is directed clockwise? $(3$pt$)($d$)$ What$$s the magnitude of the magnetic force acting on segment ab of the loop? $(4$pt$)($e$)$ If now loop moves with a constant acceleration a $=0\mathrm{.}1$ m$/$s$2($starting from rest$)$ and the magnetic field is constant at B $=1$ T$,$ what$$s the induced emf at t $=2$ sec$?(4$pt$)$
