Question

Two circular loops are placed with their centres separated by a fixed distance. How would you orient the loops to have:

The largest mutual inductance.
The smallest mutual inductance?

✓

Answer

When the loops have their axis at 0' the mutual inductance is maximum.
When loops have their axis at 90' then their inductance is minimum.
