Asked by Pat

A straight 1.2 m length iron rod is moved at 10 m/s through the earth's magnetic field at a location where it has magnitude 1.0 × 105 T. What is the magnitude of the induced emf between one end of the wire and the other end?

What formula do I use?

Magnetic field of
the Earth is ≈ 10^-5 T (!!!)
ε = B•l•v =1•10^- 5•1.2•10 =1.2•10^-4
