Magnetic effect of electric current on a field due to 4 wires
"Consider the four current-carrying wires described in the figure below. Each of these wires is long and straight, and carries the current I either into or out of the page, as shown."
What is the direction of the net magnetic field produced by these four wires at the center of the square?
A straight wire is carrying current along the x-axis in the +x direction. A second straight wire is carrying an equal current along the y-axis in the +y direction. Both of the wires are in the x-y plane, and all questions pertain only to the magneticfield at points in the x-y plane. Which of the following statements are true ab
Question 1: An infinitesimal current element Idl is located at the point x = 0.05m, y =0, z = 0 in a cartesian coordinate system. The current element points in the direction of the positive z-axis and has magnitude 2x10^-6 A m. Calculate the magnitude and direction of the magneticfielddue to this current element at the point
1. What is the definition of displacement current and how does it arise? Does displacement current have any real significance? Explain
2. Write down the maxwell's equations of electromagnetism, and state the laws they represent. Explain the meaning of all the symbols used.
I need some help with these question:
Two long, straight wires are oriented perpendicular to the computer screen, as shown below, in which L = 4.5 cm. The current in one wire is I1 = 3.1 A, pointing into the screen, and the current in the other wire is I2 = 4.0 A, pointing out of the screen. Find the magnitude and direction of
Show how an undeflected trajectory for a moving charge is obtained with appropriate crossed E and B fields. Draw seperate diagrams to illustrate your answer for a positive charge and a negative charge.
1. Two parallel wires, each carrying a current of I = 3.1 A, are shown below, where d = 5.2 cm. The current in wire 1 is in the opposite direction of wire 2. Find the direction and magnitude of the net magneticfield at points A, B, and C.
