thanks for the effort emmyz, ill rep u for it
i know how to use my hand , but my problem is i don't know when its the left or the right hand
yo man check this out, i) you use ur left hand when a current causes a force
i) you use ur right hand when a force causes a current EXAMPLE: such as generators you apply force on the wire to produce electricity
hope you got it good luck at ur exam tmrw, same thing goes to all students goin to do their exams tmrw, ya n wish me luck too.
