Question

Magnetic field due to a solenoid​

Answer 1

Answer:

A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside. ... The energy density of the magnetic field depends on the strength of the field, squared, and also upon the magnetic permeability of the material it fills.

Answer 2

Magnetic Field Due to Solenoid !!

A Long, tightly wound Helical Coil of insulated metallic wire is called a Solenoid.

A Solenoid can be made by wounding a copper wire on a pencil and then taking out the pencil from the windings. If You pass an Electric Current through this wire, a magnetic Field is created.

Direction Of Magnetic Field !!

• The Pattern of the magnetic field is similar to that of a bar Magnet.
• One end of the solenoid is a magnetic north pole and the other end is the magnetic south pole.
• The magnetic lines of forces are almost uniform Inside the solenoid and is directed from South pole to North pole.
• The magnetic lines of forces are non - uniform outside the solenoid and is directed from north pole to south pole.
