From the following diagram:
Each (golden) wire is exposed to the magnetic field \$B\$, while as the black wires are not. Assume current supplied from the power supply to be \$50A\$, length \$L\$, then the Lorentz force formula is:
$$ F = IL \times B$$
When \$F\$ is calculated, to find the total force ,is it multiplied \$F\$ by 3? the \$F_t\$ = \$3(F)\$
If so, how can that be true when current is \$50A\$? A bit confused how at the same current we could magnify force, of course at the cost of higher power due to increase of resistance?
