Editor's Notes
- **Current** Cut out details. Clarify that this is wireless charging, not power
- Pacemakers??
- Now the physics section. Any questions so far?
- Point out it’s a CHANGING current that creates magnetic field
- Point out it’s a CHANGING current that creates magnetic field
- Add more picture???? ** Add/say: changing magnetic field created current
- Add a transformer picture that there is no contact between the circuits
- Skip (?)
- Demo – Resonance?
- Pronounces “Chee”
- Add 2 or 3 bullet points Say A couple of summary sentences
