A long solenoid has a length of 0.54 m and contains 1900 turns of wire. There is a current of 2.5 A in the wire. What is the magnitude of the magnetic field within the solenoid?

Therefore,

Strength magnetic field at within the Solenoid,

Explanation:

Given:

Turn = N = 1900

length of solenoid = l = 0.54 m

Current, I = 2.5 A

To Find:

Strength magnetic field within the Solenoid,

B = ?

Solution:

If N is the number of turns in the length, the total current through the rectangle is NI. Therefore, Ampere’s law applied to this path gives

Where,

B = Strength of magnetic field

l = Length of solenoid

N = Number of turns

I = Current

Therefore,

Substituting the values we get

Therefore,

Strength magnetic field at within the Solenoid,

need to see circuit to get time constant

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
