What happens if a wire is parallel to magnetic field?
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.
Where is the magnetic field zero between two wires?
Where are the points where the magnetic field is zero? Solution: Using the right-hand rule again, allows one to see that the magnetic-field contributions from the two wires have opposite signs either above or below the wires, but not between them.
What is magnetic field and its formula?
The magnetic field formula contains the constant^{\mu_{0}}. This is known as permeability of free space and has a value^{\mu}_{0} = 4\pi \times 10^{-7} (T \cdot m/ A). Besides, the unit of a magnetic field is Tesla (T).
How do you calculate the magnetic force between two parallel wires?
Summary
- The force between two parallel currents I1 and I2 separated by a distance r, has a magnitude per unit length given by Fl=μ0I1I22πr.
- The force is attractive if the currents are in the same direction, repulsive if they are in opposite directions.
What happens when two parallel wires are magnetically attracted?
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.
Is the magnetic field produced by a long straight conductor perpendicular?
(a) The magnetic field produced by a long straight conductor is perpendicular to a parallel conductor, as indicated by RHR-2. (b) A view from above of the two wires shown in (a), with one magnetic field line shown for each wire. RHR-1 shows that the force between the parallel conductors is attractive when the currents are in the same direction.
How many amps do two parallel wires carry?
Two long, straight, parallel wires, 10.0 cm apart carry equal 4.00-A currents in the same direction, as shown in the figure. ( in the figure the current carrying wires are at the end of a straight 10cm line and they are each in the direction coming out of the page). point p is at the center of the 10cm line.
What is a parallel wire in a circuit?
Parallel Wires. In the series circuit arrangement, the parallel wires are linked by a connecting wire into a circuit that allows current along a single path. As a result, the current travels one way down one wire, and in the opposite direction down the second wire.
