Question

What is right hand palm rule Class 11?

Answer 1

The Right-Hand Palm Rule is used to determine the direction of magnetic force on a moving charged particle or current-carrying conductor in a magnetic field. It’s particularly useful in the context of electromagnetism and is often taught in Class 11 Physics.

Here’s how it works:

1. For a current-carrying conductor:
   

   - Imagine holding a straight wire that is carrying current in your right hand.
   - Point your thumb in the direction of the current (from positive to negative).
   - Now, spread your fingers out flat. Your fingers will point in the direction of the magnetic field created by the current.

1. For a moving charged particle:
   

   - If a charged particle is moving in a magnetic field, point your thumb in the direction of the velocity of the particle (the direction of motion).
   - Point your fingers in the direction of the magnetic field (from north to south).
   - The direction in which your palm faces will show the direction of the force acting on the particle.

Summary:

1. Thumb: Direction of current or velocity of the particle.
   

1. Fingers: Direction of magnetic field.
   

1. Palm: Direction of the force on the particle or the conductor.
   

This rule helps you visualize how forces interact with charges and currents in magnetic fields, which is an important concept in electromagnetism.
