1.	A current - carrying conductor is placed in a magnetic field. Nowanswer the following : (i) List thefactors on whichthe magntiudeof forceexperienced by conductor depends . (ii) When is themagnitude of this force maximum ? (iv) Statethe rule whihchelps in findingthe directionof motionof conductor. (iv)Ifinitially this forcewasactingfromrightto left, how will the direction of force change , if : (a) direction of magneticfield is reversed ? (b) directionof current is reversed ?
Answer» Solution :(i) The magnetic of FORCE experienced by current- carryingconductorwhenplacedin a magneticfield dependson (a) currentflowing (I),(b) lengthof conductor (I),(c) the strenght of magneticfield (B) , and (d)orientationof conductor in magnetic field . (ii)Magnitudeof forceis maximum when current- carryingconductoris placed at rightangles to the directionof magnetif field . (III) See Point Number13 UNDERTHE HEADING " Chapter At A Glane". (iv) (a) Directionof forceis reversed that is nowthe force acts from left to RIGHT . (b) Direction of forceis reversed thatin now the force acts from left toright.
