Asolenoid of radius 2.0 mm contains 100 turns of wire uniformly distributed over a length of 5.0 cm. it is located in air and carries a current of 2.0 a (i) using ampere's law, calculate the magnetic field strength b inside the solenoid 4 marks] (ii) draw a diagram clearly showing the direction of current flow in the solenoid and the direction of the magnetic field.

The magnetic field strength inside the solenoid is .

Explanation:

Given that,

Radius = 2.0 mm

Length = 5.0 cm

Current = 2.0 A

Number of turns = 100

(a). We need to calculate the magnetic field strength inside the solenoid

Using formula of the magnetic field strength

Using Ampere's Law

Where, N = Number of turns

I = current

l = length

Put the value into the formula

(b). We draw the diagram

Hence, The magnetic field strength inside the solenoid is .

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.
