A long iron bar lies along the x-axis and has current of I = 16.4 A running through it in the +x-direction. The bar is in the pr

Gre4nikov [31]

Answer:

B = 8.0487mT

Explanation:

To solve the exercise it is necessary to take into account the considerations of the Magnetic Force described by Faraday,

The magnetic force is given by the formula

$F =BILsin\theta$

Where,

B = Magnetic Field

I = Current

L = Length

$\theta =$ Angle between the magnetic field and the velocity, for this case are perpendicular, then is 90 degrees

According to our data we have that

I = 16.4A

F = 0.132N/m

As we know our equation must be modificated to Force per length unit, that is

$\frac{F}{L} = BI sin(90)$

Replacing the values we have that

$0.132 = 16.4 (1) B$

Solving for B,

$B = \frac{0.132}{16.4}$

$B = 8.0487mT$

On a straight horizontal track along which blocks can slide with negligible friction, block 1 slides toward block 2, which is in

vivado [14]

If the mass and post-collision speed of block 1 is known, the momentum of the block 2 can be determined.

<h3>What is momentum?</h3>

The momentum of an object in motion is the product of mass and speed of the object.

P = mv

<h3>Conservation of linear momentum</h3>

The principle of conservation of linear momentum states that, the sum of the initial momentum must be equal to the sum of the final momentum.

$m_1v_1 = m_2 v_2$

Thus, if the mass and post-collision speed of block 1 is known, the momentum of the block 2 can be determined.

What is the magnetic force on a 200 cm length of (straight) wire carrying a current of 30 A in a region where a uniform magnetic

Bezzdna [24]

Answer:

F = 0.112 N

Explanation:

To find the magnitude of magnetic force on the wire, you use the following formula:

$|\vec{F}|=|i\vec{L}\ X\ \vec{B}|=iLBsin\theta$ (1)

L: length of the wire = 200cm = 0.2m

i: current in the wire = 30 A

B: magnitude of the magnetic field = 0.055 T

θ: angle between the directions of L and B = 20°

You replace the values of L, i, B and θ in the equation (1):

$|\vec{F}|=(30A)(0.2m)(0.055T)sin(20\°)=0.112N$

hence, the magnetic force on teh wire is 0.112N
