What is the magnitude of the magnetic field created 4.0m away from a 10.0 A current?

Physics

kvasek [131]3 years ago
4 0

Answer:

The magnitude of the magnetic field created is 5 x 10⁻⁷ T

Explanation:

Given;

magnitude of current, I = 10.0 A

distance of the magnetic field, r = 4.0m

Apply Biot-Savart Law to determine the magnitude of of the magnetic field created;

B = \frac{\mu_oI}{2 \pi r}

where;

B is the magnitude of of the magnetic field

μ₀ is constant

I is current

r is the distance of the field

B = \frac{4 \pi*10^{-7} *10}{2 \pi*4} = 5*10^{-7} \ T

Therefore, the magnitude of the magnetic field created is 5 x 10⁻⁷ T

Consider a current carrying a wire coming out of your computer screen towards you. Which statement below correctly describes the
Ugo [173]

Answer:

1. The magnetic field encircles the wire in a counterclockwise direction

Explanation:

When we have a current carrying wire perpendicular to the screen in which the current flows out of the screen then by the Maxwell's right-hand thumb rule we place the thumb of our right hand in the direction of the current and curl the remaining fingers around the wire, these curled fingers denote the direction of the magnetic field which is in the counter-clock wise direction.

Ever current carrying conductor produces a magnetic field around it.

What provides most of the force to allow the runners to move?
kobusy [5.1K]

Answer:

When you are running the most important force that you should understand is friction. Friction is a force that opposes movement between two objects, but for runners friction makes you faster. Friction gives you a better and more efficient way to use your energy into speed.

(f) What do you mean by: (i) 1 J energy (ii) 1 W power​
max2010maxim [7]

Explanation:

Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s)

which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it's running.
