Questions tagged [magnetic-flux]

The sum normal component of a magnetic field passing through a surface.

The magnetic flux (represented by Φ or ΦB) through a surface is the surface integral of the normal component of the magnetic field B passing through that surface. The SI unit of magnetic flux is the weber (Wb) and the CGS unit is the maxwell. In EE, electromagnetic phenomenon is applied to transformers and other.

Why am I getting different flux densities?

I am trying to find the flux density at the top of the core. The current is known to be 2.5 A, the relative permeability of the core is known to be 800 H/m, and the flux is known to be 0.005 Wb. When using the following equation: Btop = φ/Atop =…

Magnetic flux induced in toroidal core and conductor position

I was just reading Electric Power Engineering by Elgerd when I came across these statements about flux I couldn't fully understand: "By experiment, we can confirm a most interesting characteristic of the flux. If we keep the iron core position…

Magnetic lines of force

Question: If two, one-inch magnets with the same “pull” strength are magnetically connected to each other, do the combined magnetic lines of force extend twice as far as if only one magnet’s line of force was measured?
