G semi-infinite wire segment that lies along the negative y axis and carries current of 548 Amperes in the positive y direction. Using the Biot-Savart law and showing your logic, determine just the DIRECTION of the magnetic field produced at point P located at (4.5 cm, 0, 0)

The magnetic field at a point (4.5, 0, 0) from the wire lying in the negative y-axis, with current flowing in the positive y-direction is directed in the positive z-direction.

Explanation:

The Biot Savart Law explains that the magnetic field experienced as a result of a wire of a particular length at a point r, from the wire is given as

dB = (μ₀/4π) ∫ (ds × ř)/r²

where ds = direction vector for the flow of current

ř = unit vector in the direction of the point where the magnetic field is required.

r = magnitude of the direction vector from the wire, to the point where the magnetic field is required.

Basically, the magnetic field is an integral sum of the vector product of ds and the unit vector in the direction of the point r where the magnetic field is required at that point all multiplied with (μ₀/4πr²)

This question requires only the direction of this magnetic field. This would be obtained from just the vector product of ds and ř.

ds = positive y-direction = (0, ds, 0)

wire segment that lies along the negative y axis and point P is located at (4.5 cm, 0, 0)

r = (4.5, 0, 0) - (0, -y, 0) = (4.5, y, 0)

Since we're not concerned about the magnitude, we can write the unit vector as

ř = (x, y, 0)

Direction of B is obtained from

(0î + dsj + 0k) × (xî + yj + 0k)

=

| î j k |

|0 ds 0|

|x y 0|

= î(0 - 0) - j(0 - 0) + k(xds- 0)

= 0î + 0j + xdsk

This means that the magnetic field at a point (4.5, 0, 0) from the wire lying in the negative y-axis, with current flowing in the positive y-direction is directed in the positive z-direction.

Hope this Helps!!!

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!
