Calculation of Lorentz Force in Generator and its mass equivalence

Click For Summary
SUMMARY

The calculation of Lorentz Force in a generator can be determined using the formula F = BIL, where B represents the magnetic field strength, I is the current, and L is the length of the wire. In this discussion, a single coil generator with 300 turns and a wire length of 92 meters is analyzed, yielding a force of 230 N when a current of 5 amps is applied with a magnetic field strength of 0.5 T. To relate this force to weight equivalent, the gravitational constant of 9.8 m/s² is referenced, indicating that 230 N corresponds to a weight of approximately 23.5 kg under Earth's gravity.

PREREQUISITES

Greetings All -
Per F=BIL I can calculate quantity of Force on coil (or magnet), when I draw certain amount of current from the generator.
So I need help in calculating the Force and then weight equivalent of it. Let's say I have Single coil [with 300 turns] generator [wire length = 92 meter], when I move that coil over Magnets in short circuit condition, I sense the opposite force [F] as current [I = 5 amp] passes through the coil. I calculate the amount of opposite force, being exerted on coil for that current as: B = (0.5 T)

F = 0.5 * 5 * 92 = 230 N/Amp.m [Am I correct in Units?], this means I feel the force of 230 N/Amp.m continuously.

Now I want to know how can I relate this force to weight equivalent? I mean when I hold 1 kg weight in my hand I feel F = 9.8 kg.m/s.s

Any help?

If you are talking about 1 g Earth gravity, then the gravitational constant 6.67 × 10 −11 Newton-metre 2-kilogram −2 is the conversion between Newtons and kg.
