How does the magnetic field depend when the current carrying conductor is attached in series or parallel. Give the formula with the discription.

The magnetic field lines around a long wire which carries an electric current form concentric circles around the wire. The direction of the magnetic field is perpendicular to the wire and is in the direction the fingers of your right hand would curl if you wrapped them around the wire with your thumb in the direction of the current.

Magentic field actually depends on the length of the consuctor but not the connection.
