What is Φ for your situation? Hint: it doesn't matter whether the currents are constant or time-varying.scrubber said:
The formula for calculating the magnetic force between two long wires carrying current is F = (μ0 * I1 * I2 * L) / (2 * π * d), where μ0 is the permeability of free space, I1 and I2 are the currents in the wires, L is the length of the wires, and d is the distance between the wires.
The direction of current flow in the wires determines the direction of the magnetic field they create. If the currents are flowing in the same direction, the wires will attract each other, and if they are flowing in opposite directions, they will repel each other.
The strength of the magnetic force between two long wires carrying current is inversely proportional to the distance between the wires. This means that as the distance between the wires increases, the magnetic force decreases.
The direction of the magnetic field created by two long wires carrying current is determined by the right-hand rule. If you point your right thumb in the direction of the current flow in the first wire, your fingers will curl in the direction of the magnetic field. The direction of the magnetic field will be opposite for the second wire.
The magnetic force between two long wires carrying current is directly proportional to the current in each wire. This means that if the currents are increased, the magnetic force will also increase, and if the currents are decreased, the magnetic force will decrease.
