Question
Describe experiment of two stationary coil which explains clectromagnetic induction.
✓
Answer
→Even if there is no relative motion between two coils, phenomenon of electromagnetic induction can be obtained.
→Two stationary coils $C _1$ and $C _2$ are shown in figure.
→Galvanometer is connected to $C _1$ and battery and key K are connected to $C _2$.
→On pressing K (closing), galvanometer shows momentary deflection & then comes to zero.
→After pressing (closing) key and keeping it in same situation, galvanometer does not show deflection.
→On releasing key (opening), galvanometer shows deflection in opposite direction.
→On repeating experiment keeping iron rod on axis of coil, very large deflection is seen in galvanometer.
→Thus, it is proved that a changing magnetic field produces electric current.

A double slit S1 - S2 is illuminated by a coherent light of wavelength $\lambda$. The slits are separated by a distance d.
