A solenoid that has length 30 cm, radius 1.2 cm, and 300 turns carries a current of 2.6 A. Find the magnitude of the magnetic field on the axis of the solenoid:

Explanation:

length, l = 30 cm

Number of turns, N = 300

Current, i = 2.6 A

number of turns per unit length, n = N / l = 300 / 0.3 = 1000

The magnetic field due to the current carrying solenoid is

B = 4 x 3.14 x 10^-7 x 1000 x 2.6

B = 3.27 x 10^-3 T

B = 3.27 mT

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
