• The purpose of right hand rule was to have a idea about the magnetic field around the current-carrying wire

• Used for finding the direction of the magnetic field around a straight current-carrying wire.

Right Hand Palm Rule - Visual Representation

• The Thumb represents the current

• The index finger represents the magnetic field

• The underneath the palm represents the force of magnetic field on the conductor

• Unlike left hand rule that talks about force of magnetic field the right hand rule is mostly about the force on moving charge / current

Right Hand Thumb Rules

• The right hand thumb rules is different than the normal right hand rule

• Both right hand palm rule and right hand thumb rule is different

• The thumb represents the direction of current

• The underneath of palm represents the direction of magnetic field

• Difference between right hand palm rule and right hand thumb rule is that the thumb rule focuses more on direction while on the palm rule it includes force
