Magnetic field strength (1 Viewer)

[theodore0307]

Is there a difference between magnetic field and magnetic field strength?

 

[tashe]

Magnetic field is the noun. - There is a magnetic field around the coil.

Magnetic field strength is used to describe the intensity (how strong) of the magnetic field. It is a vector as well (it has a direction). - The magnetic field strength around the coil is "2.0 T up the page".

Other than that, I don't know.

Yes, there is a difference between the two terms. Magnetic field is defined as a force field surrounding a magnetic pole that exerts forces on other magnetic poles placed in the field(the area of influence exerted by a magnetic force), it is not a vector quantity and is denoted by the symbol B. However, magnetic field strength, also known as magnetic flux density is a quantitative, vector quantity that is measured in tesla(T) or weber per square metre(Wb/m2). So essentially, magnetic field just refers to the existence of magnetic flux around an object due to its magnetic properties, but magnetic field strength specifically measures how much magnetic flux is in the entire magnetic field. Hope this helps a little.

Pretty much what Tashe said.

There is a difference.

A magnetic field is something generated by the domains by electric charges (This is out of syllabus a bit). So for example in a metal, all the delocalised electrons will face a particular way to produce a magnetic field.

The strength, as Tashe said is a vector. It refers to the amount of magnetic field and how magnetic the field is relative to other fields.
