At what distance on the axis, from the center of circular current carrying coil of radius r, the magnetic field becomes `1/8^(th)` of the magnetic field at centre?

The magnetic field at the centre of the current carrying coil is

The magneitc field produced at the center of a current carrying circular coil of radius r, is

The ratio of magnetic fields on the axis of a cricular current cerrying coil of radius a to the magnetic field at its centre lying on the periphery of the surface of the sphere will be .

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

The radius of a circular current carrying coil is R. The distance on the axis from the centre of the coil where the intensity of magnetic field is (1)/(2sqrt(2)) times that at the centre, will be:

A magnetic field is established by a circular current i of radius a. Find the magnetic field gradient (i.e. the derivative of the magnetic field induction vector) in the direction of the circular current's axis at a point whose distance from the centre of the turn is x.

Ratio of magnetic field at the centre of a current carrying coil of radius R and at a distance of 3R on its axis is

Use Biot-Savart law to derive the expression for the magnetic field on the axis of a current carrying circular loop of radius R . Draw the magnetic field lines due to circular wire carrying current I .
