Answer :
The magnetic field inside the solenoid has an energy density of 34.2 J/m3. A solenoid with a cross-sectional area of 17.0 cm2 and a length of 85.0 cm. A current of 6.60 is carried by 950 rounds of wire.
An electric charge, an electric current, and magnetic materials are all affected magnetically by a magnetic field, which is a vector field. A force perpendicular to the magnetic field and its own velocity acts on a moving charge in a magnetic field. A solenoid is a particular kind of electromagnet that produces a regulated magnetic field and is made of a helical coil of wire whose length is significantly higher than its diameter. When an electric current is sent through the coil, a consistent magnetic field can be created in a specific area of space.
u = B2Mo, u = (0.0092696)2/2*4*3.1416e-7, and u = 34.2J/m3.
