3. What is the magnetic permeability of ordinary iron
The μ near field pulse of non-magnetic materials seems to be equal to μ 0, while the magnetic permeability of ferromagnetic materials is very high, μ>>μ0。 The relative magnetic permeability of ferromagnetic materials is μ r=μ/μ 0, for example: cast iron is 200-400; Silicon steel sheets range from 7000 to 10000; Nickel zinc ferrite ranges from 10 to 1000; Nickel iron alloy is 2000; Manganese zinc ferrite ranges from 300 to 5000; The relative magnetic permeability of air is 1; Platinum is 1.00026; Mercury, silver, copper, carbon (diamond), lead, and other materials are all diamagnetic substances, with a relative magnetic permeability of less than 1, which is 0.
