If the earth's magnetic field has the strength B, the shuttle/satellite system is moving with a velocity v, and the tether has a length L, calculate the EMF E from one end of the tether to the other.

Question

naveenbabbar · Answer

E=BvL, where we consider only that part of B which is perpendicular to v and L.

anonymous · Answer

do you know the formula to find EMF

naveenbabbar · Answer

Use Electromagnetic Induction principles

i need answer it will be helpful if you would explain me and get me to the answer

anonymous · Answer

i am a good learner...it wont take time...lol

naveenbabbar · Answer

Whenever a conductor moves in a magnetic field, an electric field gets induced in the conductor, which creates a potential difference across its ends.

anonymous · Answer

and electric field makes voltage difference...which increases as it gets to end...I know upto there

naveenbabbar · Answer

Look for the words 'the equb. is reached where the magnetic force becomes equal to electric force. Also the electric field here is not conservative.
