GOOD MORNING..
Why and when does a current carrying conductor kept in a magnetic field experience force?
List the factors on which direction of this force depends?
Answers
ANSWER :
The drifting of free electrons of a conductor in a definite direction causes the current to flow through it. When such conductor is placed in a uniform
magnetic field, each drifted electron of a conductor experience a magnetic force. This force is collectively experience by a conductor as a whole.
Hence a current carrying conductor kept in a magnetic field experience a force. The direction of magnetic force depends on :
(i) direction of current through the conductor, and
(ii) direction of magnetic field.
Answer:
(a) A current carrying conductorproduces a magnetic field around it. When it interacts with magnetic field itexperiences a force. Direction of theforce depends upon direction ofcurrent and that of magnetic field.
Fleming's left hand rule
(b)The middle finger points in thedirection of the current. The thumb gives the direction of the force acting on the current-carrying conductor placed in the external magnetic field.
