When the magnetic field is observed from the North pole, the magnetic field emerges and and goes towards south. However, inside a magnet there is no field at all, thus forming butterfly shape lines. Hence, B stands for butterfly and due to this concept, scientists used the symbol B for magnetic induction.

What does symbol B mean in physics?
In physics, symbol B is often used to represent magnetic field. Magnetic fields are vector quantities that exert a force on moving electric charges and magnetic materials. This symbol is commonly used in equations involving electromagnetic phenomena.
Why can an induction heating process heat magnetic material faster than non magnetic material?
To heat something by induction (which is and oscillating magnetic field), the material has to react to the magnetic field. As the magnetic field is made to oscillate, the molecules of the material are pulled and vibrated in sympathy with the field and their vibration energy increases. Heat IS the vibration of molecules. Thus induction heating will work on a magnetic material but will have no effect on a material that is not magnetically susceptible.
Magnetic induction due to a short dipole?
Coulomb's law applies exactly only when the charged bodies are much smaller than the distance separating them and therefore can be treated approximately as point charge B = F /M M = 1 B = F
What three things needed to complete magnetic induction?
A changing magnetic field A conductor or coil of wire Movement between the magnetic field and the conductor (relative motion)
How is electricity produced from magnetism?
Electricity can be produced from magnetism through electromagnetic induction. When a conductor, such as a wire, moves through a magnetic field or when the magnetic field around a conductor changes, it induces an electric current to flow in the conductor. This current flow is the basis for producing electricity in generators and other electrical devices.
Why you use symbol B for Magnetic field instead of M?
The symbol "B" was historically used by Faraday for magnetic induction. Meanwhile, "M" is commonly used for magnetization in materials, so using "B" helps to differentiate between the two concepts. It also aligns with the International Electrotechnical Commission's standard symbol for magnetic flux density.
What is the causes of electromagnetic induction?
Change in magnetic flux.iechange in magnetic field (B).change in the area vector/ area of magnetic field under the closed circuit (A).The angle between area vector and magnetic field .......xomagnetic flux = cosxo . A . B
What does symbol B mean in physics?
In physics, symbol B is often used to represent magnetic field. Magnetic fields are vector quantities that exert a force on moving electric charges and magnetic materials. This symbol is commonly used in equations involving electromagnetic phenomena.
Electromagnetic induction occurs in a coil when there is a change in?
Could you specify "coil"? Generally the electromagnetic induction occures due to variation of the B-field (magnetic flux density), variation of the current, I, or a change in the total area in which an electric current span over a B-field.

Does aluminum work on induction cooktops?
Yes, aluminum cookware does not work on induction cooktops because aluminum is not magnetic and induction cooktops require magnetic materials to generate heat.
What is necessary for induction?
For electromagnetic induction, you need a conductor moving in a magnetic field.
What are the differences between induction and non-induction pans in terms of their heating capabilities and compatibility with induction cooktops?
Induction pans are compatible with induction cooktops because they are made of magnetic materials that respond to the magnetic field generated by the cooktop, heating up quickly and evenly. Non-induction pans, on the other hand, are not compatible with induction cooktops as they do not have magnetic properties and will not heat up efficiently on such cooktops.
What is magentic induction and an example of magnetic induction?
The magnetic flux density at any point my be defined as the number of linese of magnetic induction passing through a unit area held a right angle to the lines at the point and is represented by the vectore
Why is magnetic induction a vector quantity?
Magnetic field induction at a point is defined as the FORCE experienced by a unit north pole placed at that point. Since force is a vector quantity, manetic field induction also becomes a vector quantitiy.
What is the best way to describe induction?
a) The production of an electric or magnetic state by the proximity (without contact) of an electrified or magnetized body. b) The production of an electric current in a conductor by a change of magnetic field.
Explain the B-H curve?
The B-H curve, also known as the magnetization curve, represents the relationship between the magnetic field (H) applied to a material and the magnetic induction (B) it exhibits in response. It shows how magnetization changes with the strength of an external magnetic field and helps characterize the magnetic properties of a material, such as ferromagnetic materials showing hysteresis.
