Question

A Boeing 747 aircraft with a wingspan of 59.6 m is flying over the north magnetic pole on its way from New York to Beijing. The speed is 859 km/h, and the magnetic field is 1.12 gauss straight down. What is the voltage drop from wingtip to wingtip?
a) none of the answers
b)1.32 V.
c)1.12 V.
d)1.59 V.
e)1.77 V.
An open wire loop rotates around an axis lying in the plane of the loop, in a magnetic field perpendicular to that axis. The induced voltage is highest when the plane of the loop is parallel to the field. Why?
a)The flux is changing the fastest.
b)The flux is momentarily unchanging.
c)The flux is at a maximum.
d) the fkux is 0

The flux is momentarily unchanging.

The flux is momentarily unchanging.

Explanation / Answer

Voltage drop = V*B*L= 1.59 V



a)The flux is changing the fastest.
