Consider a wire of length L = 0.30m that runs north-south on a horizontal surface. There is a current of I = 0.50A flowing north

ankoles [38]

Answer:

Part a)

$F = 4.6 \times 10^{-6} N$

Part b)

$F = 8.2 \times 10^{-2} N$

Explanation:

Part a)

As we know that the magnetic force on the current carrying wire is given as

$F = i(\vec L \times \vec B)$

so we have

$F = iLB sin\theta$

$F = (0.50)(0.30)(0.5 \times 10^{-4}) sin38$

so we have

$F = 4.6 \times 10^{-6} N$

Part b)

Now magnetic field is changed to 0.55 T

so we will have

$F = (0.50)(0.30)(0.55) sin90$

$F = 8.2 \times 10^{-2} N$

D) Kirchhoff’s junction rule states that at any junction, the sum of the altimeter attained moving into and out of that junction are equal.

While

Kirchhoff’s loop rule states that the algebraic sum of the number of lifts used in any closed loop is equal to zero

Explanation:

Given that the lifts are analogous to batteries, and the runs are analogous to resistors.

So from all the figures. The resistors represent the runs while the lift represents the battery.

Kirchhoff’s junction rule states that at any junction, the sum of the altimeter attained moving into and out of that junction are equal.

While

Kirchhoff’s loop rule states that the algebraic sum of the number of lifts used in any closed loop is equal to zero
