Chapter : 2. Magnetic Effect of Current
Circular Coil
(B) Circular Coil :
fig, (b) Current circular, magnetic field straight (b)
It means that when the current flows in a circular wire (coil), the magnetic field produced has straight lines of force near the centre of the coil, as shown in figure. The parallel lines are in a plane perpendicular to the plane of the coil. Their direction is marked by the arrows.
Rule : The direction of the magnetic lines of force is related with the direction of the current by the right hand thumb rule.
The rule states :
Curl the four fingers of the right hand on the palm, keeping the thumb stretched out at right angles. The thumb is straight and the fingers are circular.
In case 1. thumb represents the direction of the current in the straight wire and curling of fingers represents the direction of the circular magnetic lines of force (figure.).
In case 2, curled fingers represents the direction of the current in circular wire and thumb represents the direction of the straight magnetic lines of force. (Figure.)
