Question

A magnetic field is shown to be directed upwards throughout some region that contains 4 current containing wires that have lengths and currents shown in the diagram. Rank the wires according to the magnitude of the magnetic force exerted by the external field. Ignore interactions that may occur between the wires.

Answer 1

\(F = ILB \sin\theta\)

Answer 2

@IrishBoy123
Okay so F1 would be ILB
F2=0
F3=(15L)(I/10)B
F4=(3I/5)(2L)sin45
?

Answer 3

looks good

Answer 4

Thanks :)
