First up to bat 🏏… Electric Fields

Second up to bat 🏏…Magnetic Fields

  • Two objects with charge moving in the same direction have magnetic attraction
  • Two objects with charge moving in opposite directions have a repulsive force
a moving charge forms a magnetic field
  • Never cross
  • Bunch at regions where the field is strongest
  • Always form closed loops
  • Start at the north pole and end at the south pole
  • Indicate direction

Third up to bat 🏏…Electromagnetism

Electromagnetism is the interaction between electric fields and magnetic fields.

Wireless Electricity Transfer

  1. Inductive Charging
  2. Magnetic Resonance Charging
  3. Radio Frequency Charging

Inductive Charging

4 = Magnetic Field

Magnetic Resonance Charging

Radio Frequency Charging

  1. Far-Field: emission of RF signals in an open space with a transmitter that locates a receiver in a certain area
  2. Near-Field: drop the device into a charging station
