The oscillating electric and magnetic field
WebbAn electromagnetic wave consisting of electric and magnetic oscillating fields. In this example, the oscillating electric field vectors are indicated in red, while the blue lines... WebbLight is an oscillating electric and magnetic field, so it is electrical and magnetic. Later: re the edit to your question, I think there are two issues. Firstly the interaction with electric charge and secondly the interaction with magnets. Light does not carry any charge itself, so it does not attract or repel charged particles like electrons.

WebbIn magnetic-resonance devices, a weak oscillating field (H′) is superimposed on a strong constant field (H), as shown in Figure 1, and its vector rotates with an angular velocity (ω) in a plane perpendicular to the direction of the strong field.If the rate of rotation (ω) of the weak superimposed field is different from the Larmor frequency (ω L) of the precessing …
WebbThus the rate of change of the magnetic flux is. Δ Φ Δ t = Δ ( B A cos θ) Δ t = B Δ A Δ t = B v ℓ, 20.34. where we have used the fact that the angle θ between the area vector and the magnetic field is 0°. Once we know the emf, we can find the current by using Ohm’s law. top law seriesWebbThe electromagnetic field propagates at the speed of light (in fact, this field can be identified as light) and interacts with charges and currents. Its quantum counterpart is … top lawn and outdoorsWebbThis is why, in the propagation of an electromagnetic wave, there is always an oscillating electric field coupled with a magnetic field oscillating perpendicular to this electric field. You cannot simply take away one of these fields.
