What will happen if current is flowing through two straight wires in same direction?

When the currents flow in the same direction the magnetic field will be opposite and the wires will attract. If the currents flow in opposite directions, the electrons will “see” a higher density of electrons in the other wire due to relativistic length contraction. And the wires will repel.

What is the direction of the magnetic field in a straight conducting wire?

The direction of the magnetic field is perpendicular to the wire and is in the direction the fingers of your right hand would curl if you wrapped them around the wire with your thumb in the direction of the current.

Is the force between two parallel current carrying wires with current in the same direction attractive or repulsive?

Let’s calculate the force between two parallel long wires carrying current. We will find that the force is attractive when the currents are in the same direction, and repulsive when they are in the opposite direction.

What are the direction of the current in the other wire?

The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.

What happens when an electric current passes through a wire?

When a current passes through a wire, a part of the electrical energy is converted into heat energy as a result of some resistance experienced by it and as a result the wire gets heated. This is known as heating effect of electric current.

Why two wires carrying current in opposite direction repel each other?

The direction of magnetic field on the conductor is determined by Fleming’s right hand rule. Thus, gives us that the direction of magnetic field turns out to be opposite to each other. This results in repulsion of the conductors carrying current in opposite directions relatively and vice versa.

What is the direction of force if two parallel wires carry current in same direction?

Thus, when two parallel wires carry current in the same direction, they exert equal and opposite attractive forces on each other. Figure 22.2. 2: Two wires that carry current in opposite directions. Two parallel wires carry current in opposite directions, as shown in Figure 22.2.

What is the direction of force between two parallel wires carrying current in opposite direction?

Two parallel wires carrying current in opposite directions repel and try to move away from each other.

How do you find the direction of current?

Using the right hand rule for the conventional current in the wire, the right thumb is pointed along the wire pointing to the left. At point the fingers curl around and point up, out of the screen. This can be verified by putting the thumb in the direction of current anywhere in the circuit.

What is electron direction?

Electrons being negatively charged flow from the negative terminal to the positive terminal of the voltage source. So, the actual direction of current should be from negative to positive terminal. However, the conventional direction had already been established firmly in scientific fraternity.

What is the direction of magnetic force when two wires attract?

Two wires carrying current in the same direction attract each other, otherwise they repel. The direction of the magnetic force can be found by using the right hand rule. The rule assumes that the current has the conventional direction (positive charges).

What happens when electric current runs in the opposite direction?

(Figure 12/a.) When the electric currents are running in the opposite direction, the spin directions of magnetic fields will be opposite according to the right thumb rule. The magnetic fields with opposite spin direction will penetrate each other material and “spin down” the overall magnetic field density.

How do you determine if a wire will repel a magnetic field?

The fingers of your right hand will wrap around the wire in the same direction as the magnetic field. With two currents flowing in opposite directions you can determine that the magnetic fields are in the same direction and will therefore repel.

How do you find the direction of a magnetic field?

An electric current creates a magnetic field. The fields attract or repel depending on their orientation. You can determine the direction of the magnetic field on a wire by imaging your right thumb pointing in the direction of the current. The fingers of your right hand will wrap around the wire in the same direction as the magnetic field.
