Asolenoid of length 2.50 m and radius 1.70 cm carries a current of 0.110 a. determine the magnitude of the magnetic field inside if the solenoid consists of 2200 turns of wire.

magnetic field is 0.122 mT

Explanation:

Given data

length = 2.50 m

radius = 1.70 cm

current = 0.110 A

turns of wire = 2200

to find out

magnitude of the magnetic field

solution

we know the relation of current turn and length with magnetic field i.e

magnetic field = ( μ × turn × current ) / length

here μ is permeability

magnetic field = ( μ × turn × current ) / length

magnetic field = ( 4π × × 2200 × 0.110) / 2.50

magnetic field = ( 4π × × 2200 × 0.110) / 2.50

magnetic field =  0.000122

so magnetic field is 0.122 mT

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
