What is the inductance of a coil if the coil produces an emt of 2.60 v when the current in it changes from -29.0 ma to +33.0 ma in 17.0 ms. express your answer using three significant figures.

0.712 mH

Explanation:

The emf produced by the coil = 2.6 V

Current is changes from -29 mA to 33 mA so change in current di =33-(-29)=62 mA

The time duration that is dt=17 ms

The emf is given by

So the value of inductance will be 0.712 mH

it is easily magnetized.
