At a point on the Earth’s surface the magnetic field has a horizontal component due north of 1.8 ́ 10-5 T and a vertical component downwards of 5.5 ́ 10-5 T.

(i) Draw a diagram.

(ii) Calculate the force on a 1.5 m length of wire carrying a current of 13 A when the wire is held vertically with the current flowing downwards.

(iii) Calculate the force when the wire is horizontal with the current flowing west to east.

At the equator, the earth’s field is essentially horizontal; near the north pole, it is nearly vertical. In between, the angle varies. As you move farther north, the dip angle, the angle of the earth’s field below horizontal, steadily increases. Green turtles seem to use this dip angle to determine their latitude. Suppose you are a researcher wanting to test this idea. You have gathered green turtle hatchlings from a beach where the magnetic field strength is 50μT and the...
