Calculate the reluctance of a magnetic coil which is wounded uniformly...
The reluctance (R) of a magnetic coil wound uniformly on an iron core can be calculated using the formula:
R = (l / (μ0 * μr * A))
where:
R = reluctance
l = length of the magnetic circuit (in meters)
μ0 = permeability of free space (4π * 10^-7 H/m)
μr = relative permeability of the iron
A = cross-sectional area of the core (in square meters)
First, we need to convert the length of the magnetic circuit from centimeters to meters:
l = 70 cm = 0.7 m
Next, we need to convert the cross-sectional area of the core from square centimeters to square meters:
A = 5 cm^2 = 5 * 10^-4 m^2
Now we can calculate the reluctance:
R = (0.7 / (4π * 10^-7 * 1400 * 5 * 10^-4))
R = (0.7 / (4π * 10^-7 * 1400 * 5 * 10^-4))
R ≈ 3.6 H^-1
Therefore, the reluctance of the magnetic coil is approximately 3.6 H^-1.
R = (l / (μ0 * μr * A))
where:
R = reluctance
l = length of the magnetic circuit (in meters)
μ0 = permeability of free space (4π * 10^-7 H/m)
μr = relative permeability of the iron
A = cross-sectional area of the core (in square meters)
First, we need to convert the length of the magnetic circuit from centimeters to meters:
l = 70 cm = 0.7 m
Next, we need to convert the cross-sectional area of the core from square centimeters to square meters:
A = 5 cm^2 = 5 * 10^-4 m^2
Now we can calculate the reluctance:
R = (0.7 / (4π * 10^-7 * 1400 * 5 * 10^-4))
R = (0.7 / (4π * 10^-7 * 1400 * 5 * 10^-4))
R ≈ 3.6 H^-1
Therefore, the reluctance of the magnetic coil is approximately 3.6 H^-1.
