Why do two parallel current-carrying wires attract each other?
Two parallel wires carrying currents in the same direction attract each other due to magnetic interaction between two wires carrying currents because the current in a wire produces a magnetic field and the magnetic interaction is of attractive nature when current in the two parallel wires is in the same direction.
What happened when two current-carrying wires placed near to each other?
The direction is obtained from the right hand rule. Note that two wires carrying current in the same direction attract each other, and they repel if the currents are opposite in direction.
Why do 2 parallel wires attract?
So if you have two current-carrying, parallel wires with magnetic fields circling around them in the same direction, they will attract each other, as shown in the tutorial; at the point at which their respective magnetic fields intersect, they are traveling in opposite directions, and opposites attract.
When current is parallel to?
Solution. If the current direction is parallel to the magnetic field, then there will no force on the conductor exerted by the magnetic field. Hence, the force experienced by current carrying conductor is \(0\).
Why is there no force when current and magnetic field are parallel?
A B-field exerts force on a moving charge, in a direction perpendicular to the B field. A B-field exerts force on a moving charge, in a direction perpendicular to the motion of the charge. By similar reasonong to above, this also means the force must be zero when B and the velocity of the charge are parallel.
What happens when a wire goes through a magnetic field?
When a current carrying wire is placed in a magnetic field, it experiences a mechanical force. And the force will be maximum if the current carrying wire is placed in a direction perpendicular to that of the magnetic field. The force exerted on the wire is known as the Lorentz force.
