Answer 1

explanation:

magnetic field due to a current in solenoid is due its influence,

when current passes from a solenoid we consider it as a whole piece,

then current is passing from a spiral path and it makes a magnetic field at every point electrons passing makes a magnetic field.

When field is considered as a whole it makes perpendicular to solenoid, rings of magnetic field

that creat a whole magnetic field around the solenoid and this solenoid is then working as a bar magnet of poles with North at the point where +ve terminal is attached & then south is at where -be terminal is attached......

May this help you.......,

Answer 2

Answer:

\_(ツ) Hi!!

☆ About solenoid - A construction like a coil made by a conducting wire wound closely and separately in the form of a cylinder is called solenoid.

The magnetic field resulting from solenoid is showing in the figure above (see in the attachment) . It is same as that due to bar magnet . Thus end of one the solenoid behave as north pole and the other end as South Pole . In the inner region of solenoid , the field lines are parallel indicating that the magnetic field is uniform at every point inside the solenoid .

The strength of the magnetic field produced by the solenoid is directly proportional to the number of turns of the solenoid and the current passes through it .
