2002 Nov Paper 3 Question 8:
Fig. 8.1 shows a long straight wire between the poles of a permanent magnet.
It is connected through a switch to a battery so that, when the switch is closed, there is a
steady current in the wire.
(wire in a direction at right angles to the page)
How can we find the direction of the movement of wire..I know by using fleming's L.H.R but there is no direction for current given?Or maybe i didnt understood the question :S
