What is the direction of magnetic field?????????????????????????????????/

To  determine the direction of the magnetic force on a positive moving charge, ƒ, point the thumb of the right hand in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F.in this way we can determine the direction of magnetic field.

TO determine the direction of magnetic field we can use the right hand thumb rule,right hand palm rule.

    if the current carrying conductor is held in the palm of the right hand in such a way that the thumb points in the direction of the current and the curling of the 4 fingers gives the direction of magnetic field.

 

Hello Prabhakar

                              Using the right hand and pointing the thumb in the direction of the moving positive charge or positive current and the fingers in the direction of the magnetic field the resulting force on the charge points outwards from the palm. The force on a negatively charged particle is in the opposite direction.

                         To  determine the direction of the magnetic force on a positive moving charge, ƒ, point the thumb of the right hand in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F.in this way we can determine the direction of magnetic field.This is the direction of magnetic field.

we can simply say that the direction of magnetic field can be expressed by right thumb rule.put your thumb along the direction of the current and curl your fingers towards the tangent it shows the direction of the magnetic field.

if the current carrying conductor is held in the palm of the right hand in such a way that the thumb points in the direction of the current and the curling of the 4 fingers gives the direction of magnetic field.magnetic field depend on right hand thumb rule.RIGHT HAND THUMB RULE:

the direction of magnet field is defined as using  the right hand and pointing the thumb in the direction of the moving positive charge or positive current and the fingers in the direction of the magnetic field the resulting force on the charge points outwards from the palm. The force on a negatively charged particle is in the opposite direction.

the direction of magnetic field can be find or expressed by right hand thumb rule ,firstly you need to put your thumb along the direction of current then you need to curl your fingers towards tangent to the field.
