Physics · Electromagnetic Induction
Find the mutual inductance (M) in an arrangement where a small circular loop of wire of radius R is placed inside a large coplanar square loop of wire of side L, assuming L >> R and their centres coincide.
- 1M = √2 μ0 RL2
- 2M = 2√2 μ0 R2L✓
- 3M = 2√2 μ0 RL2
- 4M = √2 μ0 R2L
Correct answer
M = 2√2 μ0 R2L
