How can you obtain magnetic field pattern of a straight current carrying conductor?

How can you obtain magnetic field pattern of a straight current carrying conductor?

Expert Answer:

1. Take a thick straight conductor XY and pass it through the centre of a thick cardboard.
2. Pass current through the conductor such that it flows from X to Y.
3. Sprinkle some iron filings on the cardboard and gently tap.
4. These concentric circles represent the magnetic field lines.

What is the shape of current carrying conductor?

Solution. The magnetic field produced by a current-carrying solenoid is similar to the magnetic field produced by a bar magnet. Therefore, the shape of the given current-carrying conductor is solenoid.

What is the shape of a current carrying conductor whose magnetic field is uniform?

Solenoid

What can we use to find the shape of a magnetic field?

Detecting magnetic fields A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction of the Earth’s magnetic field, or the magnetic field of a magnet.

What does flux mean?

The noun flux describes something that constantly changes. If your likes, dislikes, attitudes, dreams, and even friends are changing all the time, you may be in flux. Flux can also mean being unsure about a decision.

What is flux unit?

In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or ΦB. The SI unit of magnetic flux is the weber (Wb; in derived units, volt–seconds), and the CGS unit is the maxwell.

What is basic flux?

It is similar to Acidic flux but only difference is that we take basic substances like CaO for welding process or extractive metallurgy or Smelting. Basic fluxes like lime (CaO), magnesium oxide (MgO) are used to remove acidic gangue such as SiO2.

What is a flux rate?

Flux as flow rate per unit area. In transport phenomena (heat transfer, mass transfer and fluid dynamics), flux is defined as the rate of flow of a property per unit area, which has the dimensions [quantity]·[time]−1·[area]−1. The area is of the surface the property is flowing “through” or “across”.

What is the difference between flow and flux?

As nouns the difference between flow and flux is that flow is the movement of a fluid while flux is the act of flowing; a continuous moving on or passing by, as of a flowing stream.

Is work the same as flux?

Flux is a different notion from work even though they use similar concepts. Work is a measure of how much →F agrees with γ′. However, in surfaces, flux tells us how much →F tries to “go through” the surface. In contrast, it is maximal when →F is perpendicular to the surface at every point.

What is the use of flux?

The main purpose of the flux is to prepare the metal surfaces for soldering by cleaning and removing any oxides and impurities. Oxides are formed when metal is exposed to air and may prevent the formation of good solder joints.
