Asolenoid has 100 turns per cm and a total resistance of 60 ω center of the solenoid when it is connected to a 12 volt battery determine the magnetic field in the 21 a flat c

2.5 x 10^-3 T

Explanation:

n = 100 turns / cm = 10000 turns / m, R = 60 ohm, V = 12 V

i = V / R = 12 / 60 = 0.2 A

Magnetic field due to solenoid is

B = μ0 x n x i

B = 4 x 3.14 x 10^-7 x 10000 x 0.2

B = 2.5 x 10^-3 T

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
