#### What current is needed in 2 wire to produce magnmetic field

Two infinite, thin wires are oriented in the x-direction. One is at the origin, carrying a current of 1A. The second wire is at (0,20cm,0) carrying a current I in the same direction. What current is needed in the second wire to produce 0 magnetic ..

#### What transmitter powers are needed at each transmitters

Assuming a 24 dB link margin is needed to account for fading and loss due to heavy rainfall on the longest link, while 12 dB link margin is sufficient for the shorter link, what transmitter powers are needed at each of the four transmitters
