Final answer:The magnitude of the magnetic field due to a long straight wire carrying current i can be calculated using the formula B = μ0i / 2πd. The net magnetic field is the sum of the magnetic fields due to each current-carrying wire, taking into account the direction of each magnetic field if there are more than one.Explanation:The magnitude of themagnetic fieldBnet due to a long straight wire carrying current i can be expressed by using the formulaB = μ0i / 2πd, where μ0 is the permeability of free space and d is the distance from the wire. This formula comes fromAmpere's law,which relatesmagnetic field and electric current. We also know that magnetic fields from different sources add vectorially, so in a system with more than one wire carrying current, thenet magnetic fieldwould be the sum of the magnetic fields due to each wire.For example, if we have three straight wires carrying currents i1, i2, i3 and they are located at distances d1, d2, d3 from the point of interest, the net magnetic field at that point would beBnet = μ0i1 / 2πd1 + μ0i2 / 2πd2 + μ0i3 / 2πd3. This assumes the magnetic fields due to the wires add constructively. If they have different directions, we will need to find the vector sum taking into account the direction of each magnetic field.Learn more about Magnetic field magnitude here:brainly.com/question/32767823#SPJ11...
