this sent LOL
"within the limits of experimental accuracy"
=D

its given in the ques .. meaning tht the readings may vary a little than wat the theory has to say .. due to factors lik heat .. volume .. etc . :)

no probs......  8)


for calculating gradient, the ms says
triangle method seen
More than ½ line used
Gradient value correct

what do they mean by "more than 1/2 line used"   ??


takin suppose last two readigns of the gradient ..
so tht u get a uniform , accurate gradient ..

It is the current u get when u cross magnetic field lines with a conductive wire. This is the process in A.C Generators. U have a magnet, and a wire which is crossing the magnetic field lines. Everytime it crosses it, a current moves thro the wire (INDUCED) and if u have an ammeter in the circuit/wire u will see that there is current

When electric/magnetic field lines cut each other in a coil a small amount of current is produced which deflects the reading on an ammeter ..
when u insert a magnet to and fro into a coil. some current  is produced
transformers work on electromagnetic induction .. where the field lines primary coil cuts the secondary coil to either 'step up' a current or step down step up means to hav a small amount of voltage to be increased using  a lesser input voltage , step down is exactly opposite ..  :)
