EMF induced in a condoctor moving in a magnetic field.

EMF in a Bullet. At the equator, the earth's magnetic field is approximately horizontal and is directed toward the north and has a value of X.

Part A
Estimate the emf induced between the top and bottom of a bullet shot horizontally at a target on the equator if the bullet is shot toward the east. Assume the bullet has a length of 1 cm and a diameter of 0.4 cm and is traveling at 300

. EMF in a Bullet. At the equator, the earth's magnetic field is approximately horizontal and is directed toward the north and has a value of .

Part A
Estimate the emf induced between the top and bottom of a bullet shot horizontally at a target on the equator if the bullet is shot toward the east. Assume the bullet has a length of 1 cm and a diameter of 0.4 cm and is traveling at 300 .

The induced emf is given by
Blvsin´ü▒ = 8*10-5*0.4*10-2*300*sin900 = 9.6*10-5 V
9.6*10-5

V

Part B
Which is at higher potential, the top or bottom of the bullet?

The direction of induced current is ...

Solution Summary

The EMF induced in a bullet moving in earths magnetic field is calculated as well as the magnetic field in a solenoid is derived.
