State the rule to determine the direction of a
(i) magnetic field produced around a straight conductor-carrying current,
(ii) force experienced by a current-carrying straight conductor placed in a magnetic field which is perpendicular to it, and
(iii) current induced in a coil due to its rotation in a magnetic field.
Answer
(i) magnetic field produced around a straight conductor-carrying current
It is determined with the help of Maxwell’s right hand thumb rule.
(ii) force experienced by a current-carrying straight conductor placed in a magnetic field which is perpendicular to it
It is determined with the help of Fleming’s left-hand rule.
(iii) current induced in a coil due to its rotation in a magnetic field
It is determined with the help of Fleming’s right-hand rule.
