Figure shows a conducting loop placed in a magnetic field. The flux through the loop changes due to
\( \mathrm{P} \)
change in magnetic field according to the equation \( \phi \) \( =5 t-10 t^{2} \). What is the direction and magnitude of induced current at \( t=0.25 \mathrm{~s} \) ?
(1) \( 0.45 \mathrm{~A}, \mathrm{~A} \) to \( \mathrm{B} \)
(2) \( 0.5 \mathrm{~A}, \mathrm{~B} \) to \( \mathrm{A} \)
(3) \( 1.5 \mathrm{~A}, \mathrm{~A} \) to \( \mathrm{B} \)
(4) Zero
