Magnetic Effects of Electric Current
Right hand Thumb Rule
Question 1 State Fleming's Right hand thumb rule? Right hand Thumb Rule If a current carrying conductor is imagined to be held in right hand such that thumb points in direction of current, then curled fingers of hand indicate the direction of magnetic field. If current flows in upward direction then direction will be anticlockwise. If current flows in downward … [Read more...] about Right hand Thumb Rule
Magnetic Field due to a Current through a Straight Conductor
Question 1 On what factors does the intensity of magnetic field due to current carrying conductor depends? Magnetic Field due to a Current through a Straight Conductor (1) Take a battery, rheostat, an ammeter, a plug key and a long straight thick copper wire. (2) Insert the thick wire through the centre, normal to the plane of a rectangular cardboard. Take care … [Read more...] about Magnetic Field due to a Current through a Straight Conductor
Magnetic Field Lines due to Current carrying Conductor
Question 1 Draw the pattern of line of forces due to magnetic field associated with a current carrying straight conductor? Question 2 How the magnetic field produce changes with an increase in current in the straight conductor? Magnetic field lines due to Current Carrying Conductor When a conductor carries current, a magnetic field is set up around conductor.
