Question

Write right-hand thumb rule and right-hand rule.

Answer 1

Answer:

Explanation:

Right Hand Thumb rule : Hold a current carrying conductor in right hand , such that let the thumb points the towards the direction of current. Then wrap the fingers areound the conductor, and the finger points the direction of the field lines of magnetic field.

The right hand rule states that: 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.

Answer 2

Answer:

Right Hand Rule

• this is a convent Ja rule for finding out the direction of the magnetic field produced by a current flowing through an electrical conductor.
• imagine that you have held the conductor in your right hand in such a way that you are thumb points in the direction of the current.
• then turn your finger around the conductor the direction of the finger is in the direction of the magnetic lines of force.

Right hand rule

• three directional concert in the Fleming right hand rule
• 1. direction of the magnetic field 2.direction of the induced current 3. direction of the conductor
• strach the thumb, the index finger and the middle finger in such a way that they will be perpendicular to each other .
• in this position, that indicate the direction of motion of the conductor, the index finger the direction of the magnetic field, and the middle finger shows the direction of the induced current .
• this rule is known as Fleming right hand.
