Force between two perpendicular currents

In summary, the force of a wire on another wire perpendicular to it is zero due to the parallel magnetic field lines created by one wire. This is explained by the Biot-Savart law and can be visualized by using the Right-Hand Rule on one wire while considering the torque caused by the other wire's magnetic field.

its because the magnetic field lines dut to one wire will be parallel to the another wire. And as the magnetic force is ilbsin(x) ad here the x is 0.

the net force would be zero, but the net torque would not be. if you sketch this situation, and draw some field lines by one wire only (call it #2), you can use the RHR applied to wire #1, and because of #2's magnetic field, there would be a torque which would tend to make the two wires align parallel and carry current in the same direction.
 

Related to Force between two perpendicular currents

What is the force between two perpendicular currents?

The force between two perpendicular currents is a phenomenon in electromagnetism where two parallel conductors carrying electric currents experience a force on each other due to their magnetic fields interacting with each other.

How is the force between two perpendicular currents calculated?

The force between two perpendicular currents can be calculated using the following equation: F = (μ0 * I1 * I2 * L) / (2 * π * d), where F is the force in Newtons, μ0 is the permeability of free space, I1 and I2 are the currents in the two conductors, L is the length of the conductors, and d is the distance between them.

What is the direction of the force between two perpendicular currents?

The direction of the force between two perpendicular currents can be determined using the right-hand rule. If the currents are flowing in the same direction, the force will be attractive, and if they are flowing in opposite directions, the force will be repulsive.

What factors affect the force between two perpendicular currents?

The force between two perpendicular currents is affected by the strength of the currents, the distance between the conductors, and the length of the conductors. It is also influenced by the magnetic permeability of the materials surrounding the conductors.

What are some practical applications of the force between two perpendicular currents?

The force between two perpendicular currents is used in various applications, such as electric motors, generators, and transformers. It is also used in particle accelerators to control the motion of charged particles.
