 pls explain how to use right hand thumb rule, left hand thumb rule, left hand palm rule and right hand palm rule to find magnetic field inside a current carrying conductor

Fleming’s left hand rule:

When a current carrying wire is placed in a magnetic field, the wire experiences a force. Fleming’s Left Hand rule gives direction of the current, magnetic field and the force experienced by the wire.

You can see the direction of the magnetic field, the direction of the current. The direction of the force experienced by the wire is shown in the illustration:

Fleming’s right hand rule:

Fleming’s Right Hand Rule is used to find the direction of the induced emf of a conductor moving in a magnetic field. This rule is also called the Generator rule.

The thumb, the first and the second fingers on the right hand are held so that they are at right angles to each other.

If the first finger points in the direction of the magnetic field and the thumb in the direction of the motion of the conductor then the second finger will point in the direction of the induced current in the conductor.

In the illustration I’ve shown how current induced in the coil can be found using the Right Hand rule.

Maxwell’s right hand thumb rule:

The right hand thumb rule indicates the direction of magnetic field for a know direction of current. If the thumb of the right hand points along the direction of current then the curled fingers of that hand gives the direction of the magnetic field due to the current.

When thumb is upwards the curled fingers are anti-clockwise. So, magnetic field is anti-clockwise.

When thumb is downwards the curled fingers are clockwise. So, magnetic field is clockwise.

it's very simple, if u want to find direction of magnetic field for straight wire u first point thumb of right hand toward current direction and then curl your fingers, direction in which u curl ur fingers is direction of magnetic field produce around wire.

if u want to find direction of magnetic field of circular current loop, first curl fingers of right hand in direction of current and then thumb will autmoatically give u direction of magnetic field.

if u want to find direction of magnetic field due to current carrying conductor this are only two rule's we follow.

if u want to find direction of magnetic field due to small current carrying conductor we use biot savarat law's

  magnetic field is in direction of cross product of (dl * r) where dl is in direction of current and r vector is in direction pointing toward position where u have to find direction of magnetic field. to find direction we use right hand rule, first curl your fingers fom dl vector to r vector  then thumb give direction of magnetic field.
