Oct 22, 2011· Difference between 'magnetic field strength' and 'magnetic flux density'? ... I've seen another term for magnetic field strength and that is "magnetic flux density". You can sort of think of magnetic flux as the "amount of field lines" passing through an area. Density should remind you to the fact that these field lines may be closer together ...

• ### What Is Magnetic Flux Density? (with pictures)

Aug 30, 2019· Magnetic flux density is analogous with features of electric and gravitational fields. Electrical field strength is the force acting on a body per unit charge, and gravitational field strength is the force acting on a body per unit mass. Magnetic fields are created by a electric current. Magnetic flux density (B) is force (F) acting on a ...

Thanks for the careful analysis of this. I started looking into it because when we discussed wireless chargers on the radio programme I suggested that this technology is only useful over short distances; the reason I put forward was that the base coil (the driver) produces an alternating field that dies away according to 1/r^2 and that therefore the slave coil resident in the device and ...

• ### What is electric field strength? Definition from

The fieldstrengthvsdistance curve is a direct inverse function, and not an inversesquare function, because electric field strength is specified in terms of a linear displacement (per meter) rather than a surface area (per meter squared). An alternative expression for the intensity of an electric field is electric flux density.
