Magnet Field Current


<div class="wp-block-create-block-problemblock">Two long straight parallel wires are separated by a distance of 25 cm.  One is carrying a current of 2 A, the other 4 A (the currents are aimed in the same direction) .  What is the magnetic field, ##\vec{B}## at a point directly in the middle of the wires?</div>
