Best ResponseYou've already chosen the best response.0force will always be perpendicular to the plane containing the direction of magnetic field and the wire.

Best ResponseYou've already chosen the best response.1but either way it will be perpendicular to both the Length of the wire and B

Best ResponseYou've already chosen the best response.1use 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

Best ResponseYou've already chosen the best response.1V 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?

Best ResponseYou've already chosen the best response.1qVxB 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)

Best ResponseYou've already chosen the best response.1oh k. In both ways of u guys @timo86m and @experimentX and in my way the answer comes as the same

Best ResponseYou've already chosen the best response.1Well you have to use your formula either way Sin(theta) *ILB but you need IL x B to know that L curls into B :)
