What is the unit of measure of magnetic field?

Correct answer: (d) Tesla

Explanation

The SI unit of magnetic field (magnetic flux density, B) is the Tesla (T), where 1 T = 1 Weber per square metre (Wb/m²).

It is named after the scientist Nikola Tesla; the CGS unit Gauss relates as 1 T = 10,000 G.

Ampere measures current and Ohm measures resistance, while 'Cobalt' is an element, not a unit.
