From the free-body diagram in the figure, the tensions in the supporting leads go to zero when the gravitational and magnetic forces balance each other. Two long, parallel wires are hung by cords of length 5.0 cm, as shown in the accompanying figure. find the magnetic force between two wires? And does one exert a net torque on the other? Ans: So if we have two current-carrying which are said to be parallel wires with magnetic fields circling that are around them in the direction which is same, they will attract each other which is at the point at which their respective magnetic fields intersect. Due to relative length contraction, if the currents flow in opposite directions, the electrons have an increased density of electrons in the other wire. The official definition of the ampere is: One ampere of current through each of two parallel conductors of infinite length, separated by one meter in empty space free of other magnetic fields, causes a force of exactly 2107 N/m2107 N/m size 12 {2 times "10" rSup { size 8 { - 7} } " N/m"} {} on each conductor. Answer: From the formula of the two parallel wires we substitute the values, F/L = 4 *10 (-7) T*m/A * 2 A * 1 A/ (2 *0.1 m) = 4*10 (-6) N/m 2) Two wires which feels a force per unit length of 20*10 (-6) N/m, carry a current I 1 = 2 A and I 2 = 1 A respectively. Calculating Forces on Wires Two wires, both carrying current out of the page, have a current of magnitude 5.0 mA. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. This force is responsible for the pinch effect in electric arcs and other plasmas. The Use which is of the right-hand rule is to show that the force which is between the two loops in Figure 3 is said to be attractive. What is the distance between the wires? So option 1 is correct and option 2 is wrong. That is, 1 C = 1 A s. For both the ampere and the coulomb, the method of measuring force between conductors is the most accurate in practice. 6 mins. Some of our partners may process your data as a part of their legitimate business interest without asking for consent. The density of magnetic field lines indicates the strength of the magnetic field. (b) What is the magnitude and direction of the force per unit length if the currents flow in the same direction? Force per unit length on both wires fab = fba = f = 10-3 N. The force per unit length on wires is given as, fab = fba = f = 0IaIb / 2d (1). The magnitude of the force acting on each wire is equal, but the directions are opposite. For a current I 1 = Amperes and radial separation between wires r = m, the magnetic field at wire 2 is B = Tesla = Gauss. Eddy currents flow in closed loops within conductors, in planes perpendicular to the magnetic field. This also provides us with a method for measuring the coulomb. is the force per unit length, d is the distance between wires, Ia and Ib One carries a current of 2.0 A, the other a current of 5.0 A. On a section of length, \(l\), of the first wire, the magnetic force from the magnetic field, \(\vec B_{2}\), has magnitude: \[\begin{aligned} F_{1}=I_{1}||\vec l\times\vec B_{2}||=I_{1}lB_{2}\frac{\mu_{0}I_{1}I_{2}}{2\pi h} \end{aligned}\]. Thus we can pen it down as follows: Q1. The force is attractive if the currents are in the same direction, repulsive if they are in opposite directions. A magnetic field line gives the direction of the magnetic field at any point in space. This also highlights that the magnetic field (and the electric field) is just a mathematical tool that we use to, ultimately, describe the motion of charges or compass needles. calculations simply at a faster pace in just a fraction of seconds. In large circuit breakers, such as those used in neighborhood power distribution systems, the pinch effect can concentrate an arc between plates of a switch trying to break a large current, burn holes, and even ignite the equipment. Plugging these values into the equation, F = ilBsin ( ) Determine the magnitude and direction of electric current on wire Q. If two long parallel wires 1 m apart each carry a current of 1 A, then the force per unit length on each wire is 2 x 10 - 7 N/m.

Easy View solution The student is asked to show that for two current-carrying loops, the force exerted on loop 2 by loop 1 is. The infinite, straight wire shown in the accompanying figure carries a current [latex]{I}_{1}. Also, the currents flowing in the same direction make the conductors attract each other and that showing in the opposite direction makes the conductors repel each other. where,d is the distance between two conducor,Ia is the current in a conductor,Ib is the current in b conductor, Problem 1: Two long parallel wires separated by 0.1 m carry currents of 1A and 2A respectively in opposite directions. Identify the Problem Any time you are asked about EMF or current in a loop (real or imagined), you have electromagnetic induction during any period of time in which the amount of magnetic flux through the loop changes. Only the sides of the square parallel to the inifinite wire contribute to the force. We know that the magnetic field due to long straight wire, Therefore, B1 = B2 (d / 2x) = d2 / 2(0.1 + x). Two current-carrying wires attract each other magnetically: The bottom wire has current I1, which creates magnetic field B1. Due to a current carrying conductor their exists a magnetic field around it. Then if we suppose that the two long straight wires run perpendicular to one another without touching. Thus, from the two studies that we can say that any two current carrying conductors that when placed near each other will exert a magnetic force that is on each other. if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[336,280],'physicscalc_com-box-4','ezslot_7',107,'0','0'])};__ez_fad_position('div-gpt-ad-physicscalc_com-box-4-0'); We generally use the cross product to get the magnetic force between If we have three wires which are the parallel in the same plane as it is shown in Figure 2 which is with currents in the outer two running in opposite directions that is it possible for the middle wire to be repelled by both.
