Question

Magnetic field due to a current through a circular loop in hindi

Answer 1

Magnetic field due to current in a circular loop

The shape of the magnetic flux lines : To identify the shape of the magnetic lines , carry out the following steps :

Spread iron filings on a board surrounding a circular loop carrying electric current .Tapping it gently , the iron filings arrange themselves .

Observation :

The flux lines near the center of the loop are no longer circularThe magnetic flux density changes from point to point .The magnetic flux lines at the center of the loop are straight parallel lines perpendicular to the plane of the coil .

Conclusion :

The magnetic filed due to a current in a circular loop is similar to the magnetic field of a shortmagnet .The magnetic field at the center of the coil isuniform so , the magnetic filed lines are parallel and perpendicular to the plane of the coil .
