The magnetic field on the axis of a circular current loop (Eq. 5.41) is far from uniform (it falls off sharply with increasing z

Allisa [31]

Answer:

Part b

$B = 8\frac{\mu_o I}{5\sqrt5 R}$

Explanation:

Part a)

Let the radius of the coil is R and magnetic field on its axis is given as

$B = \frac{\mu_o I R^2}{2(z^2 + R^2)^{3/2}}$

now we know that two coils are identical and we need to find magnetic field between two coils

so we will have net magnetic field given as

$B = \frac{\mu_o I R^2}{2(z^2 + R^2)^{3/2}} + \frac{\mu_o I R^2}{2((d-z)^2 + R^2)^{3/2}}$

Now we know that magnetic field is maximum at position

$\frac{dB}{dz} = 0$

so we will have

$z - (d - z) = 0$

$z = \frac{d}{2}$

so it will be at mid point of two coils

Part b)

Now we know that

$\frac{d^2B}{dz^2} = 0$

so we will have

$d = R$

now magnetic field is given as

$B = 2\frac{\mu_o I R^2}{2(z^2 + R^2)^{3/2}}$

put z = 0.5 R

$B = 8\frac{\mu_o I}{5\sqrt5 R}$

An amusement park ride consists of a rotating circular platform 11.1 m in diameter from which 10 kg seats are suspended at the e

frozen [14]

To solve this problem we will use the relationship given between the centripetal Force and the Force caused by the weight, with respect to the horizontal and vertical components of the total tension given.

The tension in the vertical plane will be equivalent to the centripetal force therefore

$Tsin\theta= \frac{mv^2}{r}$

Here,

m = mass

v = Velocity

r = Radius

The tension in the horizontal plane will be subject to the action of the weight, therefore

$Tcos\theta = mg$

Matching both expressions with respect to the tension we will have to

$T = \frac{\frac{mv^2}{r}}{sin\theta}$

$T = \frac{mg}{cos\theta}$

Then we have that,

$\frac{\frac{mv^2}{r}}{sin\theta} = \frac{mg}{cos\theta}$

$\frac{mv^2}{r} = mg tan\theta$

Rearranging to find the velocity we have that

$v = \sqrt{grTan\theta}$

The value of the angle is 14.5°, the acceleration (g) is 9.8m/s^2 and the radius is

$r = \frac{\text{diameter of rotational circular platform}}{2} + \text{length of chains}$

$r = \frac{11.1}{2}+2.41$

$r = 7.96m$

Replacing we have that

$v = \sqrt{(9.8)(7.96)tan(14.5\°)}$

$v = 4.492m/s$

Therefore the speed of each seat is 4.492m/s
