Question

why and when does a current carrying conductor kept in a magneu field exprence force ? list the factor on which direction of this force depend?

Answer 1

Mention the factors on which the direction of force experienced by a current carrying conductor placed in a magnetic feild depend

a) Mention the factors on which the direction of force experienced by a current carrying conductor placed in a magnetic feild depend.
b) Under what condition is the force experienced by a current carrying conductor placed in a magnetic feild maximum?
c) A proton beam is moving along the direction of a magnetic field. What fo

 The direction of force experienced by a current carrying conductor placed in a magnetic field depends on the direction of the current in the conductor and the direction of the applied magnetic field. This is given by Fleming's left hand rule. 


Fleming’s left hand rule



If the forefinger, middle finger and thumb of the left hand are stretched such that they are at right angles to each other, then:The forefinger gives the direction of the magnetic field.

       •  The middle finger points in the direction of the current.
       •  The thumb gives the direction of the force acting on the current-carrying conductor placed in the external magnetic field. 

(b) The force experienced by a current carrying conductor is maximum when the current and magnetic field are at right angles to each other. 

(c) Since the proton beam is moving along the magnetic field the force acting on the proton beam is zero.
