A 45 cm long conductor is placed in a homogeneous magnetic field of a flux density 0.6 T, perpendicular to the lines of force. Calculate the voltage induced in the conductor if it is moved at a velocity of 8 m / s in a direction perpendicular to the lines.
if we twist the loop by 
around its diameter and the radius of the loop is 8 cm.
and the ground speed of the airplane is 830 km/h.
is placed perpendicular to the magnetic force in a homogeneous magnetic field of a flux density that increases by 0.2 T every second. Calculate how much current is induced in the loop with an internal resistance of
