Explanation Given: Wires are closely overlapped at points 2 and 3. Magnetic field strength at point 1 is 20 mT , out of the plane. Formula used: The magnetic field due to infinite straight wire carrying uniform current is, B = μ 0 I 2 π r (1) B → = B → a + B → b (2) Calculation: The magnetic field at point 1 is out of the paper, therefore, the direction of the current is from 1 to 2 throughout the wire. The wire is overlapped at point 2, the direction of the current in overlapped by is in the same direction. Hence, the magnetic field strength is becoming twice (due to the vector sum of the magnetic field using equation (2)) i

Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequen…
