# Hey, probably really stupid physics question for A2... watch

1. OK, so magenetic flux density is 'perpendicular force per unit length on a conductor carrying unit current,'
So why is it not measured in (perpendicular) newtons per coulomb when the charges causing the field on the electrons in the field is 1x10^16, like in an electric field?

If you don't know, please tell me if i've given the wrong definition or something. If you don't know full stop, thanks for clicking lol

2. Because i'm sending this Q to a phys teacher if noone can ans xxx

Flux density is force per unit current length.
B is defined as the force per unit ampere meter from the equation

B=F/Il
F = force on the wire, I = current in wire, l = length of wire
where the current is at right angles to the field.
So its units must be (in the SI system)
newton per ampere per meter
This is given its own name, Tesla.
4. Mag flex density is strength of magnetic field per unit area ......
where mag flex=BA ............b-mag field strength a - area

if its not perpedicular then is mag flex=BAcos'angle'
