Which among the following is used to find out the direction of magnetic field lines around a current carrying straight conductor?
Answer:
To find out the direction of magnetic field lines around a current-carrying straight conductor, the right-hand grip rule or right-hand thumb rule is used. According to this rule, if you point the thumb of your right hand in the direction of the current, then the direction in which the fingers wrap around the conductor will indicate the direction of the magnetic field lines around the current-carrying conductor. This rule helps in determining the orientation of the magnetic field around a straight conductor carrying an electric current.
