- The energy in an electromagnetic wave is divided equally between electric and magnetic vectors.
- Both electric and magnetic field vectors are parallel to each other and perpendicular to the direction of propagation of the wave.
- These waves do not require any material medium for propagation.
- Both electric and magnetic field vectors attain the maxima and minima at the same place and the same time.
- parallel currents repel and antiparallel cur¬rents attract.
- parallel currents attract and antiparallel cur-rents repel.
- both currents attract. ’
