Pick out the unit of magnetic permeability.(a) TmA(b) \(\frac {Tm}{A}\

1.	Pick out the unit of magnetic permeability.(a) TmA(b) \(\frac {Tm}{A}\)(c) \(\frac {T}{mA}\)(d) \(\frac {Am}{T}\)This question was addressed to me during an online interview.My query is from Magnetic Properties of Materials topic in division Magnetism and Matter of Physics – Class 12
Answer» RIGHT CHOICE is (B) \(\FRAC {Tm}{A}\) The explanation: Magnetic permeability (μ) of a magnetic SUBSTANCE is defined as the ratio of its magnetic induction (B) to the magnetic intensity (H). The expression for magnetic permeability is given as: μ=\(\frac {B}{H}\) Magnetic permeability is the ability of a magnetic substances to permit magnetic field lines to pass through it. The SI unit for this quantity is \(\frac {Tm}{A}\).
