Find , the magnitude of the magnetic field generated bythiswire at a point P located a distance from the center of thewire. Assume that at P the angle subtendedfrom the midpoint of the wire to each end is as shown in the diagram.Express your answer in terms of,,, and .Now find , the magnetic field generated by this wireat a point Plocated a distance from either end of the wire.Assume that at P the angle subtendedfrom the end of the...
A wire carries a 20.00-A current has been curved as shown in Figure . What is the magnetic field at point O? Where R= 10cm, α=2π/3.
Conductive,circular copper loop of radius a and resistance R,moves with constant velocity V in uniform magnetic field of induction B,which is normal to the plane of loop. (see the photo on the link https://ibb.co/8rkGG8X)What's the voltage between A and B and current through loop?
A loop is oriented in external magnetic field as shown in the picture. A magnetic field suddenly vanishes. When viewed from north, what is the sense of the induced current in this loop as the field fades? N B W E S the induced current flows clockwise the induced current flows counterclockwise the current flows clockwise initially, and then it flows counterclockwise before stopping there is no induced current in this loop
An electron enters into a uniform magnetic field directed into of the page. The magnetic field has a magnitude of B = 1.57. The electron will travel a semi-circle path with a radius of R=42 x 10-6 m and hits a detector. What speed did the electron have when it entered the uniform magnetic field? Electron Charge:q=1.602 x 10-19 C Electron Mass: m = 9.109 x 10-31 kg ( XB R V Detector 1.11 x 107 m/s Any electrons will...
