To find out the required absolute magnetic permeability of nickel, we will use the formula: μа = μ0 * μr, where μ0 is the magnetic constant (const, μ0 ≈ 1.2566 * 10-6 N / A ^ 2 (1.2566 * 10-6 H / m)); μr is the relative magnetic permeability of nickel (μr = 100 … 1100, according to the condition we take μr = 300).
Let’s perform the calculation: μа = μ0 * μr = 1.2566 * 10-6 * 300 = 376.98 * 10-6 N / A ^ 2 (376.98 * 10-6 H / m).
Answer: The required absolute magnetic permeability of nickel, according to the calculation, is 376.98 * 10-6 N / A2 (376.98 * 10-6 H / m).
