WebA magnetic field is basically used to describe the distribution of magnetic force around a magnetic object. Magnetic fields are created or produced when the electric charge/current moves within the vicinity of the magnet. Here, the sub-atomic particle such as electrons with a negative charge moves around creating a magnetic field. WebSimilarities. Both magnetic and electric fields at a point are inversely proportional to the square of the distance between the field source and the point in question. Electric field due to a point charge (Coulomb’s law) is: E = (1/4πƐ o) × (q/r 2) Magnetic field due to a moving charge (Biot-Savart law) is: B = (μ o /4π) × Idl (sinθ)/r 2. consulting frameworks to memorizeWebFeb 20, 2024 · Each segment of current produces a magnetic field like that of a long straight wire, and the total field of any shape current is the vector sum of the fields due … edward custom alarms
