force will always be perpendicular to the plane containing the direction of magnetic field and the wire.

but either way it will be perpendicular to both the Length of the wire and B

use right hand ruledw:1337272446404:dw think of your knuckles as L and tip of fingers as B and F is where your thumb points too. Sorry about drawing :P

V need to use right hand rule or fleming's left hand rule? I remember that in the right hand rule the thumb points towards the direction of the current. Am I right? am nt sure?

qVxB the first term always curls into the second term Then use right hand rule Knuckles is first term, tip of fingers is second term and thumb is the product (force)

oh k. In both ways of u guys @timo86m and @experimentX and in my way the answer comes as the same

Well you have to use your formula either way Sin(theta) *ILB but you need IL x B to know that L curls into B :)
