I am trying to find the magnetic field at the point in the middle of the picture can someone give a hint on how to approach the problem?
Homework Equations
The Attempt at a Solution
tomfrank said:would the left and the right side cancel out...
So I have to do it just for the bottom side?
tomfrank said:so thus this integral work :
B= ([tex]\mu[/tex]*I)/(4*pi*x)[tex]\int[/tex] between(-pi/4) and (pi/4) of cos ([tex]\theta) d\theta[/tex]
1/r^2 = cos^2(theta')/ x^2
tomfrank said:yes the picture with the angle is exactly what I was thinking...what are the limits for the integral angles?
tomfrank said:i did to -45 to 45...will that work?
An open loop magnetic field refers to a magnetic field that does not form a complete loop or circuit. This means that the magnetic field lines do not return to their starting point, but instead continue on indefinitely.
An open loop magnetic field is typically created by passing an electric current through a conductor, such as a wire. The current creates a magnetic field around the conductor, which can be visualized as a series of concentric circles perpendicular to the direction of the current.
An open loop magnetic field has several key properties, including strength, direction, and polarity. The strength of the field depends on the amount of current flowing through the conductor, while the direction is determined by the direction of the current. Polarity refers to the orientation of the field, with opposite poles attracting and like poles repelling.
Open loop magnetic fields are used in a variety of everyday devices, such as electric motors, speakers, and generators. They are also utilized in medical imaging techniques like MRI machines and in particle accelerators for scientific research.
The main difference between open loop and closed loop magnetic fields is that in a closed loop, the field lines form a complete loop or circuit, while in an open loop, they do not. This has implications for the strength and direction of the field, as well as the behavior of objects within the field.
