Calculating Tension in Horizontal Wire due to Magnetic Field

AI Thread Summary
To calculate the tension in the vertical wires supporting a horizontal wire in a magnetic field, the force on the wire can be determined using the formula F = ILB, where I is the current, L is the length of the wire, and B is the magnetic field strength. The weight of the wire, calculated as mass times gravity, must be considered alongside the magnetic force to find the total tension. The tension in the vertical wires is the sum of the forces acting on the horizontal wire, which includes both the magnetic force and the weight of the wire. Understanding the direction of these forces is crucial for accurate calculations. The discussion emphasizes the relationship between magnetic forces and gravitational forces in determining wire tension.

Homework Statement


A wire CD (mass = 50 g, length = 40 cm) is suspended horizontally by two vertical wires (both at 90 degrees /hanging straight down) which conduct a current I = 8.0 A. The magnetic field in the region is into the paper and has a magnitude 60 mT. Calculate the force on the horizonatal wire only, and hence determine the tension in each vertical wire.

Homework Equations



I have the force on the electric field as F = ILB. But I can't find anything in the book or notes relating the force on the wire to it's weight?

The Attempt at a Solution



Tension = mass x gravity ?

:cry: Electricity and Magnetism just doesn't click with me like the rest of physics does...

The wire tension is equal to the sum of all forces on the wires distributed among the wires. Positive tension being in the direction that would stretch the wire. Find all forces acting on the horizontal wire and the directions of those forces and add them up.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Correct statement about a reservoir with an outlet pipe'

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
