What happens to the direction of force experienced by a conductor placed in a magnetic field , if the direction of 1) current is rversed 2) magnetic field is reversed 3) both magnetic field and current is reversed ?
Answers
Explanation:
The force experience by a current carrying conductor placed in a magnetic field is :
F = I ( L× B ) = ILBsinθ
If the direction of current flow is reversed then the V will also change its direction and eventually the direction of force will also be reversed.
Answer:
According to Fleming's left Hand Rule rule, extend the thumb, forefinger, and the middle finger of the left hand in such a way that all the three are mutually perpendicular to each another. If the forefinger points in the direction of the magnetic field and the middle finger in the direction of the current, then, the thumb points in the direction of the force exerted on the conductor.So, if the current is reversed in the conductor placed in a magnetic field the direction of force is also reversed.
