State the rule to determine the direction of a
(a) magnetic field produced around a straight conductor-carrying current,
(b) force experienced by a current-carrying straight conductor placed in a magnetic field which is perpendicular to it, and
(c) current induced in a coil due to its rotation in a magnetic field

(a) “Right-hand thumb rule”
Right-hand Thumb Rule:
According to this rule, if the fingers of the right hand grip the wire with the thumb pointing in the direction of the current, the fingers show the direction of the magnetic field.
(b) “Fleming’s left-hand rule”
Fleming’s Left-hand Rule: According to this rule, stretch the forefinger, middle finger and thumb of your left hand such that they are mutually perpendicular to each other. If the forefinger and the middle finger point in the direction of magnetic field and the current respectively, then the thumb will point in the direction of motion or the force acting on the conductor.
(c) “Fleming’s right-hand rule”
Fleming’s Right-hand Rule: According to Fleming’s right-hand rule, stretch the forefinger, central finger and the thumb of your right Magnetk fie!d hand, mutually at right angles to each other. If the forefinger points m the direction of magnetic field and thumb denotes the direction of motion of conductor, the central finger gives the direction of flow of induced current.
