Rule 1 is for determining the direction of the magnetic force on a current-carrying wire located in a region with a magnetic field due to some other source.
When the magnetic force relationship is applied to a current-carrying wire, the right-hand rule may be used to determine the direction of force on the wire. From the force relationship above it can be deduced that the units of magnetic field are Newton seconds /(Coulomb meter)...
Right-Hand Rules: A Guide to finding the Direction of the Magnetic Force. Fmagnetic - The force a magnetic field exerts on a moving charge.
'Directionally' means these rules do not show the magnitude but show the direction of any of the three parameters (magnetic field, current, force)
Diagram of moving charge, magnetic force, and magnetic field line on a hand making the right-hand rule gesture. Current in a wire.
Ampère's right hand screw rule. Prediction of direction of field (B), given that the current I flows in the direction of the thumb.
The right hand rule is a way to predict the direction of a force in a magnetic field.
, (Equation 19.7: The magnetic force on a current-carrying wire) where is the angle between the current direction and the magnetic field. The direction of the force is given by a right-hand rule that follows the rule for charges.
The direction of the force due to a magnetic field is perpendicular to the direction of motion. Magnetic Field Produced By a constant current.
The right hand rule is applied when determining Lorentz force.
