A horizontal power line carries a current of 7250 A from south to north. Earth's magnetic field (65.7 µT) is directed toward the north and is inclined downward at 70.0° to the horizontal. Find the (a) magnitude and (b) direction of the magnetic force on 140 m of the line due to Earth's field.

a) , b) From east to west.

Explanation:

Vectorially, the magnetic force can be calculed by the following formula:

The cross product is:

a) The magnitude of the magnetic force is:

b) The direction of the magnetic force is:

From east to west.

it would be kevlar ^^

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
