Aconductor of length 0.8 m carrying a current of 2.5 a is kept in a magnetic field of 0.6 tesla. what is the magnitude of the force experienced by the conductor if it is inclined at an angle 30° to the direction of the magnetic field?

Currents in dc transmission lines can be 100 a or higher. some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers. for a line that has current 150 a and a height of 8.0 m above the ground, what magnetic field does the line produce at ground level? express your answer in teslas and as a percentage of the earth’s magnetic field, which is 0.50 g. is this value cause for worry?
