1. The problem statement, all variables and given/known data The conductive bar CD with a length of 20 cm and resistance R, moves with speed v=5 m/s. The magnetic field is perpendicular with the plan and the induction is B=2 T. The mass of the object in the figure is m=80 grams and g=10 m/ s^2 a) find the direction and the intensity of the induced current that moves in CD b) The resistance of this bar 2. Relevant equations http://s1171.photobucket.com/albums/r549/Elaia06/?action=view¤t=hrtfg.jpg 3. The attempt at a solution the resultant force on the bar is zero.This means the only force acting on the bar is the magnetic force F=B*i*l. Now we have the Tension= mg-ma but acceleration is zero so we write Magnetic force = Force on the string B*i*l=m*g I know how to solve this now The magnetic force will have the direction <---- based on the figure and the induced current the direction from left to right .
