WebApr 12, 2024 · Magnetic field in a solenoid formula is given as B = μ 0 nl. In the formula, B represents the magnetic flux density, μ 0 is the magnetic constant whose value is 4π x 10-7 Hm-1 or 12.57 x 10-7 Hm-1, N represents the number of turns, and I is the current flowing through the solenoid. Magnetic field in a long solenoid is homogeneous and its … WebAnswer: - If a wire carrying an electric current is formed into a series of loops, the magnetic field can be concentrated within the loops. The magnetic field can be strengthened even more by wrapping the wire around a core. The atoms of certain materials, such as iron, nickel and cobalt, each behave like tiny magnets. WebA solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside. Solenoids can convert electric current to mechanical action, and so are very commonly used as switches.
