## woleraymond Group Title What is the magnetic flux density midway between two long parallel wires separated by 10 cm each carrying a current of 5A. a - In the same direction b- In opposite direction What is the force per unit length exerted by each wire on the other? one year ago one year ago

You now need $B = \frac{\mu_{o} I}{2 \pi r}$ where r is the distance from the wire.
