Physics · Electromagnetic Theory
Consider a slowly charging parallel plate capacitor (distance between plates is d) having circular plates each with an area A. An electric field of magnitude E = E0 sin(ωt) exists between the plates while charging. Neglecting fringe effects, the associated magnitude of the magnetic field B at the periphery (outer edge) of the capacitor is:
- 112c2 √Aπ E0ω cos(ωt)✓
- 212c2 √Aπ E0ω sin(ωt)
- 31c2 √Aπ E0ω cos(ωt)
- 41c2 √Aπ E0ω sin(ωt)
Correct answer
12c2 √Aπ E0ω cos(ωt)
