Question

derive demension and si unit of mafnetic flux

Answer 1

hope it works

Since magnetic field strength, B, can be defined as number of flux lines per area, it means that flux is B * Area.

B is usually found by measuring the force it exerts on a current carrying wire, so it’s units can be Newtons per Ampere*meter.

That makes the units of flux, Φ=B∗Area=NA∗m∗m2Φ=B∗Area=NA∗m∗m2.


The field strength of a magnet, B, is the number of Webersm2Webersm2.
