Question

is that atom having magnetic field ?

Answer 1

Please explain what you mean so that we can help you.

Answer 2

oh atoms are magnetic:
Electrons have both orbital mechanical moment and spin.

moving charge creates magnetic field.

Electron's magnetic orbital moment due the orbital mechanical moment equals the latter multiplied by the constant named Bohr's Magneton.

Electron's magnetic moment due spin equals the spin multiplied by twice the Bohr's Magneton.

(Due to this difference the total magnetic moment of the electron is not collinear with the total mechanical moment)

Now the nuclei consist of protons and neutrons, which also have their own spin, orbital moments etc, which generally result in certain magnetic moment, not collinear to the total mechanical moment.
