Physics-Someone please recheck
posted by Russ on .
Bob Pursley rechecked my question and it was correct if you scan down but he didn't direct me where to find direction of magnetic force on plane and do the pilots have to make corrections to make up for the difference? I'd appreciate any help with that, if possible
If a aircraft flie at 1000m/s east it accumulates a 50C of charge as it passes a cloud. How would I calculate magnitude of magnetic force, direction of magnetic force on plane and do the pilots have to make corrections to make up for the difference?
Thanks in advance for any help

I forgot that the earth's magnetic field is 50 micro Tesla
Physics-Check what I have, please - Russ, Saturday, April 23, 2011 at 5:52pm
I think the formula is F = q(v*B)
so therefore I would say F= 50 C(1000*50T), correct or not??
I'm still not sure about the direction or if they have to make correctins to their controls

You have it, correct, except for units> what happened to the micro on microTesla?

Thank you for pointing that out-I totally forgot to put it back in
Could you direct me for the direction and if corrections have to be made by pilots-I'm not sure how to figure that out
The direction of the force depends upon the direction of the magnetic field, which might be neither vertical nor horizontal, but something in between. The largest it can be is
F = q V B = 50*1000*50*10^-6 = 2.5 N
If the were flying along a magnetic field line, there would be no force.
2.5 N is not enough force to require a correction. It is about the weight of a can of soda. Other forces acting on a jumbo jet plane are nearly a million times more.
