Determination of magnetic field along the axis of coil
Answers
Answer:
Explanation:
A cylindrical coil is used to create a strong magnetic field inside a domain. By wrapping the same wire many times around a cylinder, the magnetic field due to the current can become quite strong. The number of turnsspace N refers to the number of loops the cylindrical coil has. More loops will bring about a stronger magnetic field.
We will determine the magnetic field B spaceat a point Pat the axis of a cylindrical coil of length L, radius R , turns N, carrying current I. According to the Biot-Savart law, the magnetic field of a current loop is:
d B subscript Z equals fraction numerator mu subscript 0 R squared space d i over denominator 2 r cubed end fraction
If the intensity of magnetic field start a point on the axis of current carrying coil is half of that at the center of the coil, then what is the distance of that point from the center of the coil? A circular coil of radius r carries an electric current. At the centre of the circular loop, The magnetic field lines are straight. Each segment of circular loop carrying current produces magnetic field lines in the same direction with in the loop. The direction of magnetic field at the centre of circular coil is perpendicular to the place of the coil.
