Grade 12Electric Current
The horizontal component of the earth’s magnetic field at a certain place is 3.010 -5 T and
the direction of the field is from the geographic south to the geographic
north. A very long straight conductor is carrying a steady current of 1A. What is the
force per unit length on it when it is placed on a horizontal table and the direction of the
current is (a) east to west (b)south to north?
