Question

Relative permeability of nickel is 550, then its magnetic susceptibility will be ____________.

विकल्प

• `550 xx10^7`

• `550 xx 10^-7`

• 551

• 549

Answer 1

Relative permeability of nickel is 550, then its magnetic susceptibility will be 549.

Explanation:

X = `(mu_r- 1)`

X = (550 - 1) = 549
