State the rule for the direction of the magnetic field produced around a current carrying conductor. Draw a sketch of the pattern of field lines due to a current carrying conductor. Draw a sketch of the pattern of filed lines due to a current flowing through a straight conductor.

Right hand thumb rule was given by Maxwell. So this rule is also known as Maxwell’s right hand thumb rule. According to this rule, imagine that you are holding a current carrying wire in your right hand so that the thumb points in the direction of the current, then the direction in which the fingers wrap the wire will represent the direction of magnetic lines of force.
Direction of current when magnetic field direction is given is found by, MAXWELL'S RIGHT HAND THUMB RULE
◆Imagine that we are holding a current carrying conductor, Direction at which FINGERS ARE BENDED is the direction of MAGNETIC FIELD .CURRENT direction will be in the direction of your THUMB.
◆Refer the attachment given below,
◆Red - direction of Magnetic field. ◆Black - direction of current.
Here, Magnetic field is INTO the plane .Direction of current is UPWARDS.
