The force required to separate two magnetic surfaces is given by:
\(F={B^2A\over 2μ_o}\)
where, B = Magnetic flux density
A = Contact area
μo = Permittivity of free space
Calculation
Given, A = 4π cm2 = 4π × 10-4 m2
B = 1 wb/m2
μo = 4π × 10-4
\(F={(1)^2\times 4 π × 10^{ −4 } \over 2\times 4\pi\times 10^{-7}}\)
F = 500 N
