Laboratory Assignment 4: Magnetic Field Experiment Introduction: This experiment is centered around magnetic fields, with a strong focus on mathematical analysis and calculations. A) Magnetic Field Strength Calculation: We initiate the experiment by determining magnetic field strength (H) within a magnetic material. Using Ampere's Circuital Law (H = N * I), where N is the number of turns and I represents current, we calculate the magnetic field strength for different materials. B) Magnetic Flux Density Computation: Mathematical analysis is applied to compute magnetic flux density (B) within various materials. By utilizing the formula B = μ * H, where μ is the permeability of the material, we derive magnetic flux density values. C) Magnetic Field Lines and Flux Circulation: We investigate magnetic field lines and calculate the flux circulation (Φ) through different cross- sectional areas using mathematical analysis. The relationship between magnetic field lines and the circulation of magnetic flux is explored mathematically. D) Magnetic Induction Calculation: Mathematical calculations are employed to determine magnetic induction (B) within various materials. Faraday's Law (B = N * A * ΔΦ/Δt), where N represents the number of turns, A is the cross- sectional area, and ΔΦ/Δt is the change in flux, is applied to quantify magnetic induction. E)

Magnetic Field Energy: We delve into the mathematical analysis of magnetic field energy (W) in different magnetic systems. By employing the formula W = (1/2) * μ * H^2 * V, where V is the volume, we quantify magnetic field energy and explore its dependence on magnetic field strength and volume. F) Magnetic Susceptibility Calculation: Mathematical analysis is applied to calculate magnetic susceptibility (χ) for various materials. Using the formula χ = ΔM / (V * ΔH), where ΔM is the change in magnetization, ΔH is the change in magnetic field strength, and V represents volume, we derive magnetic susceptibility values. G) Magnetic Hysteresis Modeling: The experiment concludes with mathematical modeling of magnetic hysteresis. We employ mathematical models to predict the behavior of magnetic materials in response to changing magnetic fields, focusing on hysteresis loops and coercivity. Concluding Remarks: This magnetic field experiment underscores the critical role of mathematical calculations and analysis in comprehending magnetic field strength, magnetic flux density, magnetic field
