The magnetic field at a distance x on the axis of a circular coil of radius R is 1/8th of that at the centre. The value of x is

The magnetic field at a distance X from the centre, on the axis of a circular coil of radius R is 1/27 th of that at the center. The value of X is

Considering magnetic field along the axis of a circular loop of radius R , at what distance from the centre of the loop is the field one eighth of its value at the centre ?

The magnetic field at the centre of a circular coil of radius r carrying current l is B_(1) . The field at the centre of another coil of radius 2r carrying same current l is B_(2) . The ratio (B_(1))/(B_(2)) is

The ratio of magnetic induction at a point along the axis of a circular coil of radius a at a distance x to a point where x tends to zero is [x gt gt a]

What will be magnetic field at centre of current carrying circular loop of radius R?

Show that the magnetic field along the axis of a current carrying coil of radius r at a distance x from the centre of the coil is smaller by the fraction 3x^2//2r^2 than the field at the centre of the coil carrying current.

Find the magnetic field induction at a point on the axis of a circular coil carrying current and hence find the magnetic field at the centre of circular coil carrying current.

If the magnetic induction at a point on the axis of current coil is half of that at the centre of the coil, then the distance of that point from the centre of the coil is :
