Question

difference between magnetic flux and magnetic flux density

Answer 1

To explain the difference between the two consider the magnets below:Magnet A is smaller than magnet B. They both have the same “magnetism”, that is the same amount of total flux. As A has a smaller surface area than B it has a much higher “magneticstrength” or magnetic flux density

Answer 2

$\huge\bigstar \: \huge\mathrm { \underline{ \purple{answer} }} \: \bigstar \: \:$

A vector quantity measuring the strength and direction of the magnetic field around a magnet or an electric current. Magnetic flux density is equal to magnetic field strength times the magnetic permeability in the region in which the field exists.

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, and the CGS unit is the maxwell.
